flutter爬坑日记

有时候在pubspec.yaml里面加依赖库，flutter run运行的时候会报错

Error output from CocoaPods:

Error running pod install
Error launching application on iPhone 11.

其实这个问题，主要是iOS这里报错的，因为iOS需要执行pod下载依赖，我个人觉得，主要是苹果Mac的系统不同造成的，我的是苹果的M1自己的内核，如果单纯执行pod install，可能会报错的，综合上面代码提示的错误，需要执行下面命令

sudo arch -x86_64 gem install ffi
