ruby - 无法使用 rvm 在 Mountain Lion 上安装 Ruby

Question

已尝试使用 rvm 在 Mountain Lion 上安装 Ruby，但收到此错误消息:

ruby-1.9.3-p362 - #extracted to /usr/local/rvm/src/ruby-1.9.3-p362
ruby-1.9.3-p362 - #configuring

要正确安装 Ruby，我该怎么做？还安装了 Homebrew 包管理器；有冲突吗？

提前致谢。

Answer 1

这可能是因为最近版本的 OS X 使用 LLVM 而不是默认的 GCC 编译器。

试试这个:

brew update
brew tap homebrew/dupes
brew install apple-gcc42

安装 GCC 编译器。然后:

rvm install 1.9.3 --with-gcc=clang`

编辑:如果之前的解决方案不起作用，请尝试在运行 rvm install 1.9.3 之前尝试以下操作:

export CC=/usr/local/bin/gcc-4.2
