我正在特灵安装cocoapods是使用这个命令：sudo gem install cocoapods
我试过更新Ruby，卸载并重新安装Ruby，这样我就可以安装Cocoapods了。
下面是我的错误：

Building native extensions. This could take a while...
ERROR:  Error installing cocoapods:

1. sudo gem update —system我尝试运行此更新。
2. xcode-select --install，也试过这个，因为我看到有人说它对他们有效。这个也不起作用。
   任何人都面临这个问题，你是如何解决的？
