This is just enough info to get you up and running.
Much more info available via npm help once it's installed.
You need node v0.8 or higher to run this program.
To install an old and unsupported version of npm that works on node 0.3 and prior, clone the git repo and dig through the old tags and branches.
npm comes with node now.
Get the MSI. npm is in it.
Get the pkg. npm is in it.
Run make install. npm will be installed with node.
If you want a more fancy pants install (a different version, customized paths, etc.) then read on.
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 | shYou can set any npm configuration params with that script:
npm_config_prefix=/some/path sh install.shOr, you can run it in uber-debuggery mode:
npm_debug=1 sh install.shGet 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 cli.js <cmd> <args>. (This is helpful
for testing, or running stuff without actually installing npm itself.)
You can download a zip file from https://github.com/npm/npm/releases, and
unpack it in the node_modules\npm\ folder inside node's installation folder.
To upgrade to npm 2, follow the Windows upgrade instructions in the npm Troubleshooting Guide:
https://github.com/npm/npm/wiki/Troubleshooting#upgrading-on-windows
If that's not fancy enough for you, then you can fetch the code with git, and mess with it directly.
No.
So sad to see you go.
sudo npm uninstall npm -gOr, if that fails,
sudo make uninstallUsually, 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.shnpm 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/npmrcUninstalling 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.
Although npm can be used programmatically, its API is meant for use by the CLI
only, and no guarantees are made regarding its fitness for any other purpose.
If you want to use npm to reliably perform some task, the safest thing to do is
to invoke the desired npm command with appropriate arguments.
The semantic version of npm refers to the CLI itself, rather than the underlying API. The internal API is not guaranteed to remain stable even when npm's version indicates no breaking changes have been made according to semver.
If you still would like to use npm programmatically, it's possible. The API isn't very well documented, but it is rather simple.
Eventually, npm will be just a thin CLI wrapper around the modules that it depends on, but for now, there are some things that only the CLI can do. You should try using one of npm's dependencies first, and only use the API if what you're trying to do is only supported by npm itself.
var npm = require("npm")
npm.load(myConfigObject, function (er) {
if (er) return handlError(er)
npm.commands.install(["some", "args"], function (er, data) {
if (er) return commandFailed(er)
// command succeeded, and data might have some info
})
npm.registry.log.on("log", function (message) { .... })
})The load function takes an object hash of the command-line configs.
The various npm.commands.<cmd> functions take an array of
positional argument strings. The last argument to any
npm.commands.<cmd> function is a callback. Some commands take other
optional arguments. Read the source.
You cannot set configs individually for any single npm function at this
time. Since npm is a singleton, any call to npm.config.set will
change the value for all npm commands in that process.
See ./bin/npm-cli.js for an example of pulling config values off of the
command line arguments using nopt. You may also want to check out npm help config to learn about all the options you can set there.
Check out the docs, especially the faq.
You can use the npm help command to read any of them.
