npm-README (1) - Linux Man Pages
This is just enough info to get you up and running.
You need node v6 or higher to run this program.
To install an old and unsupported version of npm that works on node v5 and prior, clone the git repo and dig through the old tags and branches.
You can configure npm to use any compatible registry you like, and even run your own registry. Check out the doc on registries https://docs.npmjs.com/misc/registry.
Super Easy Install
npm is bundled with node https://nodejs.org/en/download/.
Get the MSI https://nodejs.org/en/download/. npm is in it.
Apple Macintosh Computers
Get the pkg https://nodejs.org/en/download/. npm is in it.
Other Sorts of Unices
Run make install. npm will be installed with node.
Fancy Install (Unix)
There's a pretty robust install script at https://www.npmjs.com/install.sh. You can download that and run it.
Here's an example using curl:
curl -L https://www.npmjs.com/install.sh | sh
You can set any npm configuration params with that script:
npm_config_prefix=/some/path sh install.sh
Or, you can run it in uber-debuggery mode:
npm_debug=1 sh install.sh
Get the code with git. Use make to build the docs and do other stuff. If you plan on hacking on npm, make link is your friend.
If you've got the npm source code, you can also semi-permanently set arbitrary config keys using the ./configure --key=val ..., and then run npm commands by doing node bin/npm-cli.js <command> <args>. (This is helpful for testing, or running stuff without actually installing npm itself.)
Windows Install or Upgrade
Many improvements for Windows users have been made in npm 3 - you will have a better experience if you run a recent version of npm. To upgrade, either use Microsoft's upgrade tool https://github.com/felixrieseberg/npm-windows-upgrade, download a new version of Node https://nodejs.org/en/download/, or follow the Windows upgrade instructions in the Installing/upgrading npm https://npm.community/t/installing-upgrading-npm/251/2 post.
Installing on Cygwin
So sad to see you go.
sudo npm uninstall npm -g
Or, if that fails,
sudo make uninstall
More Severe Uninstalling
Usually, the above instructions are sufficient. That will remove npm, but leave behind anything you've installed.
If you would like to remove all the packages that you have installed, then you can use the npm ls command to find them, and then npm rm to remove them.
To remove cruft left behind by npm 0.x, you can use the included clean-old.sh script file. You can run it conveniently like this:
npm explore npm -g -- sh scripts/clean-old.sh
npm uses two configuration files, one for per-user configs, and another for global (every-user) configs. You can view them by doing:
npm config get userconfig # defaults to ~/.npmrc npm config get globalconfig # defaults to /usr/local/etc/npmrc
Uninstalling npm does not remove configuration files by default. You must remove them yourself manually if you want them gone. Note that this means that future npm installs will not remember the settings that you have chosen.
Check out the docs https://docs.npmjs.com/.
You can use the npm help command to read any of them.
If you're a developer, and you want to use npm to publish your program, you should read this https://docs.npmjs.com/misc/developers.
