brew install aredridel/iojs/iojs
As of iojs 2.0.2, Homebrew ships with its own formula for iojs. This isn’t preferrable, in my opinion, since global npm packages aren’t being ran properly.
If you’d like to use this anyway, simply doing
brew install iojs is not enough. To get iojs working on Homebrew You will need to unlink
node first then use
link --force to install iojs.
brew install iojs brew unlink node brew link iojs --force
