When sourcing nvm.sh, if there are no version of node installed the command `nvm ls default` silentry fails, however it's return status code (`$?`) is still set to non-zero, which means an error. This patch simply avoids this issue by making sure the status code after sourcing is ok so that people that put the returned status codes in their command line prompt don't get an error every time `nvm.sh` is sourced. |

Node Version Manager
Installation
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 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 sources upon login.
Often I also put in a line to use a specific version of node.
Usage
To download, compile, and install the v0.4.1 release of node, do this:
nvm install v0.4.1
And then in any new shell just use the installed version:
nvm use v0.4.1
Or you can just run it:
nvm run v0.4.1
If you want to see what versions are available:
nvm ls
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 v0.4.1
Problems
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.
