Simple flavour of node/iojs binary management, no subshells, no profile setup, no convoluted api, just simple.
Note: Does not work on Windows at the moment. Pull Requests are appreciated.
$ npm install -g n
$ make install
$HOME. Prefix later calls to
$ PREFIX=$HOME make install
Install a few nodes:
$ n 0.8.14 $ n 0.8.17 $ n 0.9.6
n to prompt selection of an installed node. Use the up /
down arrow to navigate, and press enter or the right arrow to
select, or ^C to cancel:
$ n 0.8.14 ο 0.8.17 0.9.6
Use or install the latest official release:
$ n latest
Use or install the stable official release:
$ n stable
Switch to the previous version you were using:
$ n prev
Remove some versions:
$ n rm 0.9.4 v0.10.0
Instead of using
rm we can simply use
$ n - 0.9.4
When running multiple versions of node, we can target
them directly by asking
n for the binary path:
$ n bin 0.9.4 /usr/local/n/versions/0.9.4/bin/node
Or by using a specific version through
$ n use 0.9.4 some.js
$ n as 0.9.4 --debug some.js

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.
