RVM 无法在 OS x 10.9 上安装 Ruby

Question

我正在尝试使用 RVM 在我的 OS X Mavericks 笔记本电脑上安装 Ruby 和 Rails。当我跑步时：

rvm 要求

我遇到了：

Checking requirements for osx.
Installing requirements for osx.

我已经安装了最新版本的 Xcode。我试着跑了：

Xcode-select --install

但我被告知服务器上没有命令行工具。

我注意到了这一行：

checking for gcc... /usr/bin/llvm-gcc-4.2

但我认为文件应该是 /usr/bin/llvm-gcc

我需要做什么？

先安装 HomeBrew，然后运行：

rvm 要求

在 Mac OS Mavericks 上为我工作。 （提示表格How install ruby 2.1.0 on OS_X 10.9 using rvm? ( No binary rubies available for: osx/10.9/x86_64/ruby )）

在尝试符号链接之前，我尝试从命令行运行 mac 端口。我收到“-bash: port: command not found”错误。我手动下载并安装了 macports，之后一切正常。
