rbenv, but for node.

git clone -b v0.3.4 https://github.com/wfarr/nodenv.git ~/.nodenv

Then add the following to your shell config at the end:

export PATH="$HOME/.nodenv/bin:$PATH"
eval "$(nodenv init -)"

Global install

To install nodenv for usage by all users on the system, this will provide the proper environment variables to be set on login shells. Setting the group ownership allows members of the group, below creates a new group, you can use a pre-existing one also. To add a user to this group usermod -aG nodenv user

git clone -b v0.3.4 https://github.com/wfarr/nodenv.git /usr/local/lib/nodenv
sudo /usr/sbin/groupadd nodenv
sudo chgrp -R /usr/local/lib/nodenv
sudo chmod g+ws /usr/local/lib/nodenv

Then add the following to /etc/profiled.d/nodenv.sh

export NODENV_ROOT=/usr/local/lib/nodenv
export PATH=$NODENV_ROOT/bin:$PATH

eval "$(nodenv init -)"

# Make sure locally install binaries get priority
export PATH=node_modules/.bin:$PATH

Credits

This library was heavily, heavily, heavily inspired by @sstephenson's rbenv and ruby-build projects. A few ideas were also taken from nvm.

A number of patterns and utilities are borrowed from that project, and it is my hope that nodenv provides the same simplicity, elegance, and usability that I've come to love in rbenv and ruby-build for NodeJS users.
