First you'll need to make sure your system has a c++ compiler. For OSX, XCode will work, for Ubuntu, the build-essential and libssl-dev packages work.
To install you could use the install script (requires Git) using cURL:
curl https://raw.github.com/creationix/nvm/master/install.sh | sh
or Wget:
wget -qO- https://raw.github.com/creationix/nvm/master/install.sh | sh
The script clones the Nvm repository to ~/.nvm and adds the source line to your profile (~/.bash_profile or ~/.profile).
For manual install create a folder somewhere in your filesystem with the nvm.sh file inside it. I put mine in a folder called nvm.
Or if you have git installed, then just clone it:
git clone git://github.com/creationix/nvm.git ~/nvm
To activate nvm, you need to source it from your bash shell
. ~/nvm/nvm.sh
I always add this line to my ~/.bashrc or ~/.profile file to have it automatically sourced upon login.
Often I also put in a line to use a specific version of node.
To download, compile, and install the latest v0.8.x release of node, do this:
nvm install 0.8
And then in any new shell just use the installed version:
nvm use 0.8
Or you can just run it:
nvm run 0.8
If you want to see what versions are installed:
nvm ls
If you want to see what versions are available to install:
nvm ls-remote
To restore your PATH, you can deactivate it.
nvm deactivate
To set a default Node version to be used in any new shell, use the alias 'default':
nvm alias default 0.8

Tests are written in Urchin. Install Urchin like so.
wget -O /usr/local/bin https://raw.github.com/scraperwiki/urchin/0c6837cfbdd0963903bf0463b05160c2aecc22ef/urchin
chmod +x /usr/local/bin/urchin
(Or put it some other place in your PATH.)
There are slow tests and fast tests. The slow tests do things like install node and check that the right versions are used. The fast tests fake this to test things like aliases and uninstalling. From the root of the nvm git repository, run the fast tests like this.
urchin test/fast
Run the slow tests like this.
urchin test/slow
Run all of the tests like this
urchin test
Nota bene: Avoid running nvm while the tests are running.
To activate, you need to source bash_completion:
[[ -r $NVM_DIR/bash_completion ]] && . $NVM_DIR/bash_completion
Put the above sourcing line just below the sourcing line for NVM in your profile (.bashrc, .bash_profile).
nvm
$ nvm [tab][tab]
alias copy-packages help list run uninstall version
clear-cache deactivate install ls unalias use
nvm alias
$ nvm alias [tab][tab]
default
$ nvm alias my_alias [tab][tab]
v0.4.11 v0.4.12 v0.6.14
nvm use
$ nvm use [tab][tab]
my_alias default v0.4.11 v0.4.12 v0.6.14
nvm uninstall
$ nvm uninstall [tab][tab]
my_alias default v0.4.11 v0.4.12 v0.6.14
If you try to install a node version and the installation fails, be sure to delete the node downloads from src (~/nvm/src/) or you might get an error when trying to reinstall them again or you might get an error like the following:
curl: (33) HTTP server doesn't seem to support byte ranges. Cannot resume.
Where's my 'sudo node'? Checkout this link:
on Arch Linux and other systems using python3 by default, before running install you need to
export PYTHON=python2
After the v0.8.6 release of node, nvm tries to install from binary packages. But in some systems, the official binary packages don't work due to incompatibility of shared libs. In such cases, use -s option to force install from source:
nvm install -s 0.8.6
