NVM is a version manager for node.js just like RVM is for ruby. io.js is a fork of node which has more features than current node.js implementation. They may merge in the future.
I use both with NVM. I can switch between node and iojs as well as target specific versions of either one of them. Install NVM by following directions on its site.
I used Homebrew to install nvm.
brew install nvm
After installation is done…
// list all installed node versions on my machine (I have been using nvm...) nvm ls v0.8.16 v0.10.21 v0.12.4 -> system node -> stable (-> v0.12.4) (default) stable -> 0.12 (-> v0.12.4) (default) iojs -> iojs- (-> system) (default) // check what node versions are available remotely nvm ls-remote // switch to iojs nvm use iojs // switch back to node nvm use node // install node version nvm install v0.10.11 // switch to installed version nvm use v0.10.11 // uninstall a node version nvm uninstall v0.10.11 // uninstall nvm entirely rm -rf ~/.nvm ~/.npm ~/.bower
These are simple and useful tasks. See nvm site for details.
