If you bought a stand-alone version of an Office app, for example Visio or Word, in most cases you install this app in the same way you install the Office suite, by signing in to www.office.com with your Microsoft account, or work or school account and selecting Install for your stand-alone product. For python support, you will need setuptools and may need to install a python-dev or python-devel package. To build the C++ client library you will need to install libfolly. See below for some more information on options to configure your build.

This section covers the basics of how to install Python packages.

It’s important to note that the term “package” in this context is being used asa synonym for a distribution (i.e. a bundle ofsoftware to be installed), not to refer to the kind of package that you import in your Python source code (i.e. a container ofmodules). It is common in the Python community to refer to a distribution using the term “package”. Using the term “distribution”is often not preferred, because it can easily be confused with a Linuxdistribution, or another larger software distribution like Python itself.

Contents

This section describes the steps to follow before installing other Pythonpackages.

Before you go any further, make sure you have Python and that the expectedversion is available from your command line. You can check this by running:

You should get some output like Python3.6.3. If you do not have Python,please install the latest 3.x version from python.org or refer to theInstalling Python section of the Hitchhiker’s Guide to Python.

Note

If you’re a newcomer and you get an error like this:

It’s because this command and other suggested commands in this tutorialare intended to be run in a shell (also called a terminal orconsole). See the Python for Beginners getting started tutorial foran introduction to using your operating system’s shell and interacting withPython.

Note

If you’re using an enhanced shell like IPython or the Jupyternotebook, you can run system commands like those in this tutorial byprefacing them with a ! character:

It’s recommended to write {sys.executable} rather than plain python inorder to ensure that commands are run in the Python installation matchingthe currently running notebook (which may not be the same Pythoninstallation that the python command refers to).

Note

Due to the way most Linux distributions are handling the Python 3migration, Linux users using the system Python without creating a virtualenvironment first should replace the python command in this tutorialwith python3 and the pip command with pip3--user. Do notrun any of the commands in this tutorial with sudo: if you get apermissions error, come back to the section on creating virtual environments,set one up, and then continue with the tutorial as written.

Additionally, you’ll need to make sure you have pip available. You cancheck this by running:

If you installed Python from source, with an installer from python.org, orvia Homebrew you should already have pip. If you’re on Linux and installedusing your OS package manager, you may have to install pip separately, seeInstalling pip/setuptools/wheel with Linux Package Managers.

If pip isn’t already installed, then first try to bootstrap it from thestandard library:

If that still doesn’t allow you to run pip:

  • Securely Download get-pip.py1

  • Run pythonget-pip.py. 2 This will install or upgrade pip.Additionally, it will install setuptools and wheel if they’renot installed already.

    Warning

    Be cautious if you’re using a Python install that’s managed by youroperating system or another package manager. get-pip.py does notcoordinate with those tools, and may leave your system in aninconsistent state. You can use pythonget-pip.py--prefix=/usr/local/to install in /usr/local which is designed for locally-installedsoftware.

While pip alone is sufficient to install from pre-built binary archives,up to date copies of the setuptools and wheel projects are usefulto ensure you can also install from source archives:

See section below for details,but here’s the basic venv3 command to use on a typical Linux system:

This will create a new virtual environment in the tutorial_env subdirectory,and configure the current shell to use it as the default python environment.

Python “Virtual Environments” allow Python packages to be installed in an isolated location for a particular application,rather than being installed globally. If you are looking to safely installglobal command line tools,see Installing stand alone command line tools.

Imagine you have an application that needs version 1 of LibFoo, but anotherapplication requires version 2. How can you use both these applications? If youinstall everything into /usr/lib/python3.6/site-packages (or whatever yourplatform’s standard location is), it’s easy to end up in a situation where youunintentionally upgrade an application that shouldn’t be upgraded.

Or more generally, what if you want to install an application and leave it be?If an application works, any change in its libraries or the versions of thoselibraries can break the application.

Also, what if you can’t install packages into theglobal site-packages directory? For instance, on a shared host.

In all these cases, virtual environments can help you. They have their owninstallation directories and they don’t share libraries with other virtualenvironments.

Currently, there are two common tools for creating Python virtual environments:

  • venv is available by default in Python 3.3 and later, and installspip and setuptools into created virtual environments inPython 3.4 and later.

  • virtualenv needs to be installed separately, but supports Python 2.7+and Python 3.3+, and pip, setuptools and wheel arealways installed into created virtual environments by default (regardless ofPython version).

The basic usage is like so:

Using venv:

Using virtualenv:

For more information, see the venv docs or the virtualenv docs.

In both of the above cases, Windows users should _not_ use thesource command, but should rather run the activate script directlyfrom the command shell. The use of source under Unix shells ensuresthat the virtual environment’s variables are set within the currentshell, and not in a subprocess (which then disappears, having nouseful effect).

Managing multiple virtual environments directly can become tedious, so thedependency management tutorial introduces ahigher level tool, Pipenv, that automatically manages a separatevirtual environment for each project and application that you work on.

pip is the recommended installer. Below, we’ll cover the most commonusage scenarios. For more detail, see the pip docs,which includes a complete Reference Guide.

The most common usage of pip is to install from the Python PackageIndex using a requirement specifier. Generally speaking, a requirement specifier iscomposed of a project name followed by an optional version specifier. PEP 440 contains a fullspecificationof the currently supported specifiers. Below are some examples.

To install the latest version of “SomeProject”:

To install a specific version:

To install greater than or equal to one version and less than another:

To install a version that’s “compatible”with a certain version: 4

In this case, this means to install any version “1.4.*” version that’s also“>=1.4.2”.

pip can install from either Source Distributions (sdist) or Wheels, but if both are presenton PyPI, pip will prefer a compatible wheel.

Wheels are a pre-built distribution format that provides faster installation compared to SourceDistributions (sdist), especially when aproject contains compiled extensions.

If pip does not find a wheel to install, it will locally build a wheeland cache it for future installs, instead of rebuilding the source distributionin the future.

Upgrade an already installed SomeProject to the latest from PyPI.

Captain Ibanez, I quoted your info on serial numbers onthe Ibanez site and referenced your thread on the matter. The lads over there really struggle with serial numbers and i thought it would be helpful. Ibanez roadstar ii serial numbers. This website possesses NO DATABASE of guitars made by manufactures, instead simple serial code patterns that are available on this site and in the wider guitar community are used. It follows that potential scammers can use this knowledge to try to trick unsuspecting buyers. 1997 - Present - Under the old numbering scheme 1997 would show duplicate numbers to 1987 so the serial number was changed to the F and 7 digits, now the first 2 denoting year of production. F98***** is a guitar built by Fujigen in 1998.

To install packages that are isolated to thecurrent user, use the --user flag:

For more information see the User Installs sectionfrom the pip docs.

Note that the --user flag has no effect when inside a virtual environment- all installation commands will affect the virtual environment.

If SomeProject defines any command-line scripts or console entry points,--user will cause them to be installed inside the user base’s binarydirectory, which may or may not already be present in your shell’sPATH. (Starting in version 10, pip displays a warning wheninstalling any scripts to a directory outside PATH.) If the scriptsare not available in your shell after installation, you’ll need to add thedirectory to your PATH:

  • On Linux and macOS you can find the user base binary directory by runningpython-msite--user-base and adding bin to the end. For example,this will typically print ~/.local (with ~ expanded to the absolutepath to your home directory) so you’ll need to add ~/.local/bin to yourPATH. You can set your PATH permanently by modifying ~/.profile.

  • On Windows you can find the user base binary directory by running py-msite--user-site and replacing site-packages with Scripts. Forexample, this could returnC:UsersUsernameAppDataRoamingPython36site-packages so you wouldneed to set your PATH to includeC:UsersUsernameAppDataRoamingPython36Scripts. You can set your userPATH permanently in the Control Panel. You may need to log out for thePATH changes to take effect.

Install a project from VCS in “editable” mode. For a full breakdown of thesyntax, see pip’s section on VCS Support.

Install from an alternate index

Search an additional index during install, in addition to PyPI

Installing from local src in Development Mode,i.e. in such a way that the project appears to be installed, but yet isstill editable from the src tree.

You can also install normally from src

Install a particular source archive file.

Install from a local directory containing archives (and don’t check PyPI)

To install from other data sources (for example Amazon S3 storage) you cancreate a helper application that presents the data in a PEP 503 compliantindex format, and use the --extra-index-url flag to direct pip to usethat index.

Find pre-release and development versions, in addition to stable versions. Bydefault, pip only finds stable versions.

Install setuptools extras.

“Secure” in this context means using a modern browser or atool like curl that verifies SSL certificates when downloading fromhttps URLs.

2

Depending on your platform, this may require root or Administratoraccess. pip is currently considering changing this by making userinstalls the default behavior.

3

Beginning with Python 3.4, venv (a stdlib alternative tovirtualenv) will create virtualenv environments with pippre-installed, thereby making it an equal alternative tovirtualenv.

The compatible release specifier was accepted in PEP 440and support was released in setuptools v8.0 andpip v6.0

Quickstart

  1. Install Xcode and the Xcode Command Line Tools
  2. Agree to Xcode license in Terminal: sudo xcodebuild -license
  3. Install MacPorts for your version of the Mac operating system:

Installing MacPorts

MacPorts version 2.5.4 is available in various formats for download and installation (note, if you are upgrading to a new major release of macOS, see the migration info page):

  • “pkg” installers for Mojave, High Sierra, Sierra and El Capitan, for use with the macOS Installer. This is the simplest installation procedure that most users should follow after meeting the requirements listed below. Installers for legacy platforms Yosemite, Mavericks, Mountain Lion, Lion, Snow Leopard, Leopard and Tiger are also available.
  • In source form as either a tar.bz2 package or a tar.gz one for manual compilation, if you intend to customize your installation in any way.
  • Git clone of the unpackaged sources, if you wish to follow MacPorts development.
  • The selfupdate target of the port(1) command, for users who already have MacPorts installed and wish to upgrade to a newer release.

Checksums for our packaged downloads are contained in the corresponding checksums file.

Please note that in order to install and run MacPorts on macOS, your system must have installations of the following components:

  1. Apple's Xcode Developer Tools (version 10.0 or later for Mojave, 9.0 or later for High Sierra, 8.0 or later for Sierra, 7.0 or later for El Capitan, 6.1 or later for Yosemite, 5.0.1 or later for Mavericks, 4.4 or later for Mountain Lion, 4.1 or later for Lion, 3.2 or later for Snow Leopard, or 3.1 or later for Leopard), found at the Apple Developer site, on your Mac operating system installation CDs/DVD, or in the Mac App Store. Using the latest available version that will run on your OS is highly recommended, except for Snow Leopard where the last free version, 3.2.6, is recommended.

  2. Apple's Command Line Developer Tools can be installed on recent OS versions by running this command in the Terminal:

    Older versions are found at the Apple Developer site, or they can be installed from within Xcode back to version 4. Users of Xcode 3 or earlier can install them by ensuring that the appropriate option(s) are selected at the time of Xcode's install ('UNIX Development', 'System Tools', 'Command Line Tools', or 'Command Line Support').

  3. Xcode 4 and later users need to first accept the Xcode EULA by either launching Xcode or running:
  4. (Optional) The X11 windowing environment for ports that depend on the functionality it provides to run. You have multiple choices for an X11 server:
    • Install the xorg-server port from MacPorts.
    • The XQuartz Project provides a complete X11 release for macOS including server and client libraries and applications.
    • Apple's X11.app is provided by the “X11 User” package on older OS versions. It is always installed on Lion, and is an optional installation on your system CDs/DVD with previous OS versions.

macOS Package (.pkg) Installer

The easiest way to install MacPorts on a Mac is by downloading the pkg or dmg for Mojave, High Sierra, Sierra, El Capitan, Yosemite, Mavericks, Mountain Lion, Lion, Snow Leopard, Leopard or Tiger and running the system's Installer by double-clicking on the pkg contained therein, following the on-screen instructions until completion.

This procedure will place a fully-functional and default MacPorts installation on your host system, ready for usage. If needed your shell configuration files will be adapted by the installer to include the necessary settings to run MacPorts and the programs it installs, but you may need to open a new shell for these changes to take effect.

The MacPorts “selfupdate” command will also be run for you by the installer to ensure you have our latest available release and the latest revisions to the “Portfiles” that contain the instructions employed in the building and installation of ports. After installation is done, it is recommended that you run this step manually on a regular basis to to keep your MacPorts system always current:

At this point you should be ready to enjoy MacPorts!

Type “man port” at the command line prompt and/or browse over to our Guide to find out more information about using MacPorts. Help is also available.

Source Installation

If on the other hand you decide to install MacPorts from source, there are still a couple of things you will need to do after downloading the tarball before you can start installing ports, namely compiling and installing MacPorts itself:

  1. “cd” into the directory where you downloaded the package and run “tar xjvf MacPorts-2.5.4.tar.bz2” or “tar xzvf MacPorts-2.5.4.tar.gz”, depending on whether you downloaded the bz2 tarball or the gz one, respectively.
  2. Build and install the recently unpacked sources:
    • cd MacPorts-2.5.4
    • ./configure && make && sudo make install
    Optionally:
    • cd ./
    • rm -rf MacPorts-2.5.4*

These steps need to be perfomed from an administrator account, for which “sudo” will ask the password upon installation. This procedure will install a pristine MacPorts system and, if the optional steps are taken, remove the as of now unnecessary MacPorts-2.5.4 source directory and corresponding tarball.

To customize your installation you should read the output of “./configure --help more” and pass the appropriate options for the settings you wish to tweak to the configuration script in the steps detailed above.

You will need to manually adapt your shell's environment to work with MacPorts and your chosen installation prefix (the value passed to configure's --prefix flag, defaulting to /opt/local):

  • Add ${prefix}/bin and ${prefix}/sbin to the start of your PATH environment variable so that MacPorts-installed programs take precedence over system-provided programs of the same name.
  • If a standard MANPATH environment variable already exists (that is, one that doesn't contain any empty components), add the ${prefix}/share/man path to it so that MacPorts-installed man pages are found by your shell.
  • For Tiger and earlier only, add an appropriate X11 DISPLAY environment variable to run X11-dependent programs, as Leopard takes care of this requirement on its own.

Lastly, you need to synchronize your installation with the MacPorts rsync server:

Upon completion MacPorts will be ready to install ports!

It is recommended to run the above command on a regular basis to keep your installation current. Type “man port” at the command line prompt and/or browse over to our Guide to find out more information about using MacPorts. Help is also available.

Git Sources

If you are developer or a user with a taste for the bleeding edge and wish for the latest changes and feature additions, you may acquire the MacPorts sources through git. See the Guide section on installing from git.

Purpose-specific branches are also available at the https://github.com/macports/macports-base/branches url.

Forehand arms company shotgun value. Alternatively, if you'd simply like to view the git repository without checking it out, you can do so via the GitHub web interface.

Selfupdate

If you already have MacPorts installed and have no restrictions to use the rsync networking protocol (tcp port 873 by default), the easiest way to upgrade to our latest available release, 2.5.4, is by using the selfupdate target of the port(1) command. This will both update your ports tree (by performing a sync operation) and rebuild your current installation if it's outdated, preserving your customizations, if any.

Other Platforms

Install Https Centos 7

Running on platforms other than macOS is not the main focus of The MacPorts Project, so remaining cross-platform is not an actively-pursued development goal. Nevertheless, it is not an actively-discouraged goal either and as a result some experimental support does exist for other POSIX-compliant platforms such as *BSD and GNU/Linux.

The full list of requirements to run MacPorts on these other platforms is as follows (we assume you have the basics such as GCC and X11):

How To Install Https Everywhere Firefox

  • Tcl (8.4 or 8.5), with threads.
  • mtree for directory hierarchy.
  • rsync for syncing the ports.
  • cURL for downloading distfiles.
  • SQLite for the port registry.
  • GNUstep (Base), for Foundation (optional, can be disabled via configure args).
  • OpenSSL for signature verification, and optionally for checksums. libmd may be used instead for checksums.

Normally you must install from source or from an git checkout to run MacPorts on any of these platforms.

Help

Help on a wide variety of topics is also available in the project Guide and through our Trac portal should you run into any problems installing and/or using MacPorts.
