Unity：导Xcode工程报错 iOS framework addition failed due to a CocoaPods installation failure.

iOS framework addition failed due to a CocoaPods installation failure. This will will likely result in an non-functional Xcode project.

Unity导出Xcode工程时，由于其依赖了第三方的CocoaPods库，报错如下。

解决方案：

虽然错误中写的WARNING，但是解决了这个WARNING问题，也不再报错了。

cd ~
vim .profile  # 如没有，执行如下命令，如有，填入 export LANG=en_US.UTF-8
touch .profile # 新建 .profile
source .profile # 让其生效

具体报错如下（部分）：

iOS framework addition failed due to a CocoaPods installation failure. This will will likely result in an non-functional Xcode project.

After the failure, "pod repo update" was executed and succeeded. "pod install" was then attempted again, and still failed. This may be due to a broken CocoaPods installation. See: https://guides.cocoapods.org/using/troubleshooting.html for potential solutions.
