Question

我的Mac系统Ruby安装已完全中断。

我看过几篇推荐我设置RVM或rbenv的文章，但是我试图安装Xcode pod（cocoapods），而且我不知道为什么我的系统Ruby如此损坏。

运行gem时，得到以下输出：

看来，这些仅仅是弃用警告，从其他帖子中可以看出，答案只是运行gem pristine --all --no-extensions。

基本上我运行任何gem命令时，都会出现权限错误：

ERROR:  While executing gem ... (Gem::FilePermissionError)
    You don't have write permissions for the /System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/lib/ruby/gems/2.3.0 directory.

如何重置系统Ruby？我不使用Ruby，昨天我运行了命令gem install cocoapods。从那以后，它就不再可用了。

请注意，基本上，您应该使用rbenv之类的工具自行安装Ruby，但是如果您不想这样做，请参考以下答案。

已为root安装了系统Ruby，因此您需要sudo命令才能与其进行交互。尝试sudo gem install cocoapods。

（顺便说一句，gem命令，没有子命令，仅显示用法，没有破）
