c编译器不'；t工作ruby安装

我遵循指南安装多个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了。这只是猜测，几天前我确实把GCC搞砸了，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：删除-r gcc临时文件

注意：此错误仅在尝试安装1.8.7-p358版本时显示。对于1.9.3-p125，它可以正常工作

当我尝试使用rbenv安装ruby1.8.7-p358时

正在检查C编译器是否正常工作…否

试试这个：

也许您缺少一些可以用来编译C程序的包。 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

---

我正在使用OSX查看标签

brew uninstall gcc46
brew install apple-gcc42
