ruby - 无法编译 ruby​​ 1.9.3

Question

当我运行时

rvm install 1.9.3 --with-gcc=clang

在 Mac OSX Lion 上，ruby 无法编译，我在 (.rvm/log/ruby-1.9.3-p374/make.log) 中收到以下错误

如何在 Lion 上安装 ruby​​ 1.9.3？

Answer 1

使用 Xcode 4.6 我也遇到了这个问题。我在/usr/bin/gcc 中安装了使 gcc 可用的命令行工具。

我设法让它工作:

rvm install 1.9.3 --with-gcc=gcc

注意。我没有安装自制软件。
