ny

1.7.0 • Public • Published

ny (nodejs version manager)

nodejs (including io.js and supports release candidates) version manager written in bash with no subshells, no profile setup, no convoluted api, just simple.

Installation

$ npm install -g ny

or

$ make install

to $HOME. Prefix later calls to ny with NY_PREFIX=$HOME

$ NY_PREFIX=$HOME make install

Installing Binaries

Install a few nodes:

$ ny 2.5.0
$ ny 0.12.4
$ ny 4.0.0

Type ny to prompt selection of an installed iojs. Use the up / down arrow to navigate, and press enter or the right arrow to select, or ^C to cancel:

$ ny

  0.12.0
  2.5.0
ο 4.0.0

Use or install the latest official release:

$ ny latest

Use or install the stable official release:

$ ny stable

Switch to the previous version you were using:

$ ny prev

Removing Binaries

Remove some versions:

$ ny rm 0.12.5 v2.5.0

Instead of using rm we can simply use -:

$ ny - 0.12.5

Binary Usage

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

$ ny bin 4.0.0
/usr/local/n/versions/1.0.4/bin/node

Or by using a specific version through ny's use sub-command:

$ ny use 4.0.0 some.js

with flags:

$ ny as 4.0.0 --debug some.js

Details

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

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

To alter where ny operates simply export NY_PREFIX to whatever you prefer.
