Install Node.js to install n to install Node.js?

I have a problem understanding the use of n. Basically, it is clear that it is a version manager for Node.js such as nvm.

But in contrast to nvm, which is basically a shell script, according to the documentation you are encouraged to use npm to install n:

$ npm install -g n

What I don't get is: For having npm at hand you need to install Node.js. Why would I install Node.js manually to use npm to then be able to install Node.js using n?

To put my question in other words: Why does n suggest installing using npm, if its main purpose is to install Node.js, which includes npm?

n suggests using npm to install it because n is a module. That is, npm is the easiest way to install it. Node modules have the functionality of being able to run in a shell when installed globally, so that function was utilized to make switching Node versions much easier.

Frustrating because I've found this tool to be so handy on Linux.

Comments
  • Does n-install let me install multiple versions of n? :D
  • @btx9000: Yes: you can install 2 version of n right next to each other to upgrade to m.
  • I just want to add that if you get an error during "make install", you may have had installed it before. Then you should call "make uninstall" first.
  • make install fails with cp: cannot create regular file '/usr/local/bin/n': Permission denied. Maybe update the example to run with sudo?
  • Of course you are right that it's much more convenient to just type n 0.10.20 and you're done, but why not use n for the initial install? This way, the very first install feels "special". E.g.: Is it guaranteed that n uses the same folders as the Node.js installer does?
  • Because n is a module, and using npm is simply the easiest way to install it. As for your second question, Node.js binaries are stored in n's own directory, something like /usr/local/n/versions, otherwise you wouldn't be able to have multiple versions installed at the same time.
  • But the initial install isn't installed there - isn't that a problem? Please forgive me if this questions may be a little naive, but I just wonder why it is and I'm curious ;-)
  • Why would it be a problem if the initial install isn't there?
  • I'm not sure about the initial install, but for most cases n prev would just restore the previous version. Edit: It appears it also saves the initial install to /usr/local/n/versions/.prev when you first add a new version, as it does with any installation. Therefore n prev would also work in restoring the initial install.
  • :) this could be a comment maybe.
  • i'm having the same problem.
  • Crooner, @fraxture: If you installed only by cloning n's GitHub repo, then not finding any installed versions is expected: you must explicitly install them; e.g., with n stable to install the latest stable Node.js version. With neither n nor Node.js installed, you can also try curl -L http://git.io/n-install | bash, which includes installing the latest stable Node.js version - see my answer.
  • If it wasn't clear already, the error message is telling you that n has not yet installed any versions of Node, not that n itself hasn't been installed. Obviously, running n without having n installed (i.e. on your PATH) would give you a bash/ksh/zsh error message like -bash: n: command not found instead of the error message you see.
