How do I install a previous version of an npm package?
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
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
首先删除旧版本
npm install express@3.X
