Virtual Environments for Node
If you want a global
nave command, you could install this thing with npm.
But that's not really necessary. You can run the
nave.sh shell script
from here, or symlink it wherever you want.
basher install isaacs/nave
If you have npm, presumably you already have Node, so it's a tiny bit silly, but maybe you like installing the top-level Node some other way, and install your subshell version switcher with npm. Why is a bash program in npm anyway? It's fine. Bits don't judge.
npm install -g nave
Usage: nave <cmd> Commands: install <version> Install the version passed (ex: 0.1.103) use <version> Enter a subshell where <version> is being used use <ver> <program> Enter a subshell, and run "<program>", then exit use <name> <ver> Create a named env, using the specified version. If the name already exists, but the version differs, then it will update the link. usemain <version> Install in /usr/local/bin (ie, use as your main nodejs) clean <version> Delete the source code for <version> uninstall <version> Delete the install for <version> ls List versions currently installed ls-remote List remote node versions ls-all List remote and local node versions latest Show the most recent dist version help Output help information <version> can be the string "latest" to get the latest distribution. <version> can be the string "stable" to get the latest stable version.
That's about it. Enjoy.
When you're done using a specific version of node, just exit the shell to return to where you were before using nave.
$NAVEThe current shell. Either a version, or a name and version.
$NAVENAMEThe name of the current shell. Equal to
$NAVEVERSIONin unnammed environments.
$NAVEVERSIONThe version of node that the current shell is pointing to. (This should comply with
$NAVELVLThe level of nesting in the subshell.
$NAVE_DEBUGSet to 1 to run nave in
$NAVE_DIRSet to the location where you'd like nave to do its business. Defaults to
$NAVE_CONFIGSet this to an array of arguments to pass to
./configure. Defaults to
("--debug"). (Note that parens are required to supply multiple arguments. I use
("--debug" "--without-npm")on my own system, since I'm usually using nave to test npm, so installing it in the subshell doesn't help much.) This can be set in the
~/.navercfile, or in your normal
$NAVE_JOBSIf set, this will be the number of jobs to run when building node. If this isn't set, it'll use the
$JOBSenv, then try to guess a reasonable value based on the number of CPUs, then fall back on 2 if
sysctl -n hw.ncpufails.
Prior to version 0.2, nave would run programs as
However, this is somewhat more limiting, so was dropped. If you prefer the
old style, just prefix your command with
Nave requires bash. It will probably never work on Windows, or other systems lack a native Bourne Again Shell. Sorry.
Nave logins work with bash and zsh. If your shell doesn't set the
BASH environment variable, then nave assumes you're using zsh. As
such, strange archaic shells like sh, csh, tcsh, ksh, and the like will not
Nave will source
~/.naverc on initialization of a new subshell, if it
exists and is readable.
You may control the place where nave puts things by setting the
NAVE_DIR environment variable. However, note that this must be set
somewhere other than
~/.naverc, since it needs to be set in the
parent shell where the
nave command is invoked.
By default, nave puts its stuff in
~/.nave/. If this directory does
not exist and cannot be created, then it will attempt to use the location
of the nave.sh bash script itself. If it cannot write to this location,
then it will exit with an error.
nave borrows concepts, inspiration, and code from Tim Caswell's "nvm" and Kris Kowal's "sea" programs.
Sea is really nice, but is very tied to Narwhal. Also, it's a require.paths manager, which nave is not.
Nvm is also really nice, but has to be sourced rather than being run, and thus is a little bit wonky for some use cases. But it doesn't involve subshells, which makes it better for some others.
