n

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

Installation

$ npm install -g n

$ make install

Installing Binaries

Install a few nodes ("v" is optional), the version given becomes the active node binary once installation is complete.

$ n 0.2.6
$ n v0.3.3

List installed binaries:

$ n

  0.2.5
ο 0.2.6
  0.3.3

Pass some config flags to ./configure:

$ n 0.2.6 --debug

List installed binaries, config flags are shown:

  0.2.3
ο 0.2.6 --debug
  0.3.4
  0.3.5

Use or install the latest official release:

$ n latest

Use or install the stable official release:

$ n stable

Install a custom or patched version of node from a tarball:

$ n custom 0.6.5 https://github.com/dshaw/node/tarball/patch/v0.6.5status

Removing Binaries

Remove some versions:

$ n rm 0.2.4 v0.3.0

Instead of using rm we can simply use -:

$ n - 0.2.4

Binary Usage

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

Execute a script with 0.3.3 regardless of the active version:

$ n use 0.3.3 some.js

with flags:

$ n as 0.3.3 --debug some.js

Execute npm with 0.6.3 regardless of the active version:

$ n npm 0.6.3 install coffee-script
$ n npm 0.6.3 list

Usage

Output from n --help:

   n --stable                  Output the latest stable node version available
   n ls                        Output the versions of node available

 Options:

   -h, --help      Display help information

 Aliases:

   -       rm
   which   bin
   use     as
   custom  c

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 N_PREFIX environment variable.

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