I was getting this error and had to completely reinstall cocoapods to fix it. Finally worked. Maybe this solution suits for anyone else.

I was having the same exact problem, although I had the latest version of the xcode command-line tools.
尽管我有最新版本的 xcode 命令行工具，但我遇到了同样的问题。
If you have homebrew installed, do brew install apple-gcc42. This immediately solved it for me.
如果您安装了自制软件，请执行brew install apple-gcc42. 这立即为我解决了。
