I used nvm to download node v0.4.10 and installed npm to work with that version of node.

I am trying to install express using

and I get an error that express requires node version >= 0.5.0.

Well, this is odd, since I am following the directions for a node+express+mongodb tutorial here that used node v0.4.10, so I am assuming express is/was available to node v0.4.10. If my assumption is correct, how do I tell npm to fetch a version that would work with my setup?

If you have to install an older version of a package, just specify it

For example: npm install express@3.0.0

You can also add the --save flag to that command to add it to your package.json dependencies, or --save --save-exact flags if you want that exact version specified in your package.json dependencies.

The install command is documented here: https://docs.npmjs.com/cli/install

If you're not sure what versions of a package are available, you can use:

And npm view can be used for viewing other things about a package too. https://docs.npmjs.com/cli/view

First remove old version, then run literally the following:

and for stable or recent

In my opinion that is easiest and fastest way:

$ npm -v

4.2.0

$ npm install -g npm@latest-3

..

Npm Install Particular Version

$ npm -v

Npm Version String

3.10.10

you can update your npm package by using this command:

npm install <package_name>@<version_number>

example:npm install yargs@12.02

You can use the following command to install a previous version of an npm package:

I have a general way to solve this type of problems, which could be helpful too, especially when cloning repositories to run them locally, but requires a little more analysis of the versions.

With the package npm-check-updates I verify the versions of the packages (according to the package.json file) that are not declared in their latest available versions, as shown in the figure (https://www.npmjs.com/package/npm-check-updates):

With this information we can verify the update status of the different packages and make decisions as to which packages to upgrade / degrade and which ones do not.

Assuming that we decided to update all the packages as they are listed, we can use the ncu -u command which only modifies your package.json file. Run npm install to update your installed packages and package-lock.json.

Then, depending on the requirements of the repository, we can refine what is needed, installing the specific versions with npm view <package> versions and npm install <package>@<version>

npm install -g npm@version

in which you want to downgrade

npm install -g npm@3.10.10

On Ubuntu you can try this command.

Specific version : sudo n 8.11.3 instead of sudo n stable

Say you want to install a library lib-a which has dependencies dep-1 and dep-2. If lib-a has declared in its package.json to use a version of dep-2 that is out of date (say it doesn't work on node 0.8.0 which just came out), but there is a branch of dep-2 that works with node 0.8.0 - branch name node0.8.0.

So the packages in the equation are:

Cva serial number lookup. Is there a way to tell NPM to install lib-a, but use dep-2#node0.8.0 instead of dep-2?

With NPM you can install a specific branch of a project like this:

And if I were to customize the package.json of lib-a, you could tell it to use dep-2#node0.8.0 like this:

By modifying the package.json you can then run

and it will install the node 0.8.0 compatible dep-2 branch. But, that requires I have access to modifying lib-a, which for my specific case I don't. Technically, I could fork lib-a and make the above change to package.json. But in my specific case, lib-a is a dependency of another library, so I'd have to fork the project it's referenced in, and on and on..

So the question is, is there a way to tell NPM to install lib-a, and tell it to use the node0.8.0 branch of dep-2? Something like this:

That would be awesome. If it's not possible, that would be good to know so I can prepare myself to have to fork/customize the chain of projects.

NPM install syntax:

so you can choose one of these methods to install your modules.
