node version manager
My own flavour of node binary management, no subshells, no profile setup, no convoluted api, just simple.
$ npm install -g n
$ make install
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
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
Execute a script with 0.3.3 regardless of the active version:
$ n use 0.3.3 some.js
$ 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: n [options] [COMMAND] [config] Commands: n Output versions installed n latest [config ...] Install or activate the latest node release n stable [config ...] Install or activate the latest stable node release n <version> [config ...] Install and/or use node <version> n custom <version> <tarball> [config ...] Install custom node <tarball> with [args ...] n use <version> [args ...] Execute node <version> with [args ...] n npm <version> [args ...] Execute npm <version> with [args ...] n bin <version> Output bin path for <version> n rm <version ...> Remove the given version(s) n --latest Output the latest node version available n --stable Output the latest stable node version available n ls Output the versions of node available Options: -V, --version Output current version of n -h, --help Display help information Aliases: - rm which bin use as custom c
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.
