安装软件包的以前版本

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

npm install express -g

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

npm install <package>@<version>

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:

npm view <package> versions

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:

npm install express@3.X

In my opinion that is easiest and fastest way:

$ npm -v

4.2.0

$ npm install -g npm@latest-3

...

$ npm -v

3.10.10

It's quite easy. Just write this, for example:

npm install -g npm@4.6.1

Or:

npm install -g npm@latest    // For the last stable version
npm install -g npm@next      // For the most recent release

On Ubuntu you can try this command.

sudo npm cache clean -f
sudo npm install -g n
sudo n stable 

Specific version : sudo n 8.11.3 instead of sudo n stable

npm install -g npm@version

in which you want to downgrade

npm install -g npm@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:

npm install packagename@version
