Installing Ruby with RVM on Mac is a cinch, simply execute:
\curl -sSL https://get.rvm.io | bash -s stable --ruby
But recently, while trying to install RVM instead of the default Mavericks Ruby, the script that normally just “works” fails with the ominous message:
: Requirements installation failed with status: 1.
It turns out to be something funky with Mavericks and the Homebrew step of the installation. Luckily, despite the failure of the script, you can simply install Hombrew manually to solve the problem. Installing Homebrew is a triviality, simply execute the following command in Terminal:
ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"
It will first install the XCode Command Line Tools (don’t worry if you already have it, just hit “install” and let it do it’s thing) and then once the Xcode dialog disappears, hit [any] key in Terminal and it will auto-download and auto-install itself. Once its all finished (and it can take a few minutes, just be patient), simply re-execute the command to install RVM Ruby.
