# 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. Where's my 'sudo node'?
