How install ruby 2.1.0 on OS_X 10.9 using rvm? ( No binary rubies available for: osx/10.9/x86_64/ruby )

Question

I'm trying to install ruby 1.9.3-p545 or ruby-2.1.0 or ruby-2.1.1, but it fails...

My environment:

• OS_X 10.9 x86_64
• rvm 1.25.20

Error from terminal:

bmalets$ rvm install 1.9.3-p545
Searching for binary rubies, this might take some time.

Continuing with compilation. Please read 'rvm help mount' to get more information on binary rubies.

Please help.

P.S. I tried to update my command line tools, it fails too:

I tried to update ports: sudo port -v selfupdate, and it ask me for command line tools :)

bmalets$ sudo xcode-select --install
xcode-select: note: install requested for command line developer tools

Well, I got the similar problem. And I finally solved it even though I was not sure about the details... T_T

1. download the latest Command Line Tools manually from https://developer.apple.com/downloads/index.action?name=for%20Xcode%20-

2. instal Homebrew

3. run rvm requirements, and it will download some packages automatically

4. WORK!
