我正在关注this指南安装多个ruby版本。
我让我的C编译器正常工作，直到几天前我执行了下面的命令。我不记得我想做什么。这只是猜测我几天前就搞砸了GCC，这可能就是问题所在。如果我猜错了，请纠正我。正如所有这些命令所说：remove -r gcc temperory files。
注意：此错误仅在我尝试安装1.8.7-p358版本时显示。对于1.9.3-p125，它可以正常工作

答案 0 :(得分：0)
试试这个：
也许你有一些可用于编译C程序的缺失包。 尝试在终端上运行这些命令。
sudo apt-get update
sudo apt-get install build-essential
对于OSX
brew uninstall gcc46
brew install apple-gcc42
