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.
If you are searching for the latest version below 2.x.x, check out the branch "1.x.x"
With node/iojs already installed:
$ npm install -g n
or, by cloning this repo and running:
$ make install
n to subdirectory
bin/n of the directory specified in environment variable
PREFIX, which defaults to
/usr/local (note that you will likely need
sudo to install there).
To change the default to, say,
$HOME, i.e., to install
PREFIX=$HOME make install.
n downloads node/iojs versions to subdirectory
n/versions of the directory specified in environment variable
N_PREFIX, which defaults to
/usr/local; the active node/iojs version is installed directly in
To change the default to, say,
$HOME, prefix later calls to
N_PREFIX=$HOME or add
export N_PREFIX=$HOME to your shell initialization file.
Alternatively, consider third-party installer n-install, which allows installation directly from GitHub; for instance,
curl -L http://git.io/n-install | bash
$HOME/n/bin, modifies the initialization files of supported shells to export
N_PREFIX and add
$HOME/n/bin to the
PATH, and installs the latest stable node version.
As a result, both
n itself and all node/iojs versions it manages are hosted inside a single, optionally configurable directory, which you can later remove with the included
n-uninstall script; script
n itself to the latest version - see the n-install repo for details.
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
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 picks the binaries matching your system architecture, e.g.
n will download 64 bit binaries for a 64 bit system. You can override this by using the
Download and use latest 32 bit version of node:
$ n --arch x86 latest
Download and use latest 32 bit version of iojs:
$ n io --arch x86 latest

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.
