Xcode 4.3 的 rvm 要求

Question

今天我在 Mac 上工作（我是 Ubuntu 用户），在安装和配置 Ruby on Rails 时遇到了一些问题。

我首先安装 homebrew，然后安装 rvm。

然后我尝试安装 rvm 要求并收到此错误：

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 '
Xcode version older than 4.6.2 installed, download and install newer version from:

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

Xcode version older than 4.6.2 installed, download and install newer version from:

+ return 1
Requirements installation failed with status: 1.
user:~ analistas$ 

可以用旧版 Xcode 运行 rvm requirements 吗？

Answer 1

您可以使用brew search rvm，如果您看到旧版本（我不确定哪一个支持旧版 gcc）。然后你可以做brew install {whatever search returns}
