今天我在Mac（我是Ubuntu用戶）工作，並且在安裝和配置Ruby on Rails時遇到了一些問題。對Xcode 4.3的rvm要求
首先我安裝自制軟件，然後rvm。
然後我試圖安裝RVM要求和得到這個錯誤：
user:~ analistas$ rvm requirements
Checking requirements for osx.
Error: No available formula for gcc46
Installing requirements for osx.
Updating system........
Error running 'requirements_osx_brew_update_system ',
showing last 15 lines of /Users/analistas/.rvm/log/1395783259/update_system.log
+ printf %b '

After installation open Xcode, go to Downloads and install Command Line Tools.
\n'

+ return 1
Requirements installation failed with status: 1.
user:~ analistas$
有可能與年長的Xcode運行rvm requirements？
