Answer 1

I solved this problem by install "Homebrew" first :

ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"

after that I run: $ brew doctor, then it tell me:

Warning: No developer tools installed. You should install the Command Line Tools. Run xcode-select --install to install them.

so i run "xcode-select --install" ,after that i run " rvm requirements ", it works!

P.S.: If you get Error: No available formula for gcc46 /, try brew tap --repair homebrew/dupes , then try reinstalling. By the way, I use brew install gcc46, it took me more than half an hour without any prompt。

In the end, excuse me for my poor english。

You've probably not done the following : After installing xcode, launch it, navigate to Xcode->Preferences, Downloads tab. Install Command Line Tools. This will download and install C, compiler, loader and other command line utilities needed to compile & build the Ruby packages.
