n

My own flavour of node binary management, no subshells, no profile setup, no convoluted api, just simple.

Installation

$ npm install n

or

$ make install

Examples

Install a few nodes ("v" is optional):

$ n 0.2.6
$ n v0.3.3

List installed nodes:

$ n

  0.2.5
* 0.2.6
  0.3.3

Pass some config flags to ./configure:

$ n 0.2.6 --debug --oprofile

Remove some versions:

$ n rm 0.2.4 v0.3.0

Instead of using rm we can simply use -:

$ n - 0.2.4

When running multiple versions of node, we can target them directly by asking n for the binary path:

$ n bin 0.3.3
/usr/local/n/versions/0.3.3/bin/node

Usage

Output from n --help:

 Usage: n [options] [COMMAND] [config] 

 Commands:

   n                   Output versions installed
   n bin <version>     Output bin path for <version>
   n rm <version ...>  Remove the given version(s)
   n <version>         Install and/or use node <version>

 Options:

   -V, --version   Output current version of n
   -h, --help      Display help information

Details

n by default installs node to /usr/local/n/versions, from which it can see what you have currently installed, and activate previously installed versions of node when n <version> is invoked again.

Activated nodes are then installed to the prefix /usr/local, which of course may be altered via the PREFIX environment variable.

To alter where n operates simply export N_PREFIX to whatever you prefer.
