Flutter编译问题记录

问题：

运行出现以下报错

Launching lib/main.dart on macOS in debug mode... Warning: CocoaPods not installed. Skipping pod install. CocoaPods is a package manager for iOS or macOS platform code. Without CocoaPods, plugins will not work on iOS or macOS. For more info, see Using packages | Flutter For installation instructions, see CocoaPods Guides - Getting Started Error: CocoaPods not installed or not in valid state.

提示：应该是CocoaPods安装有问题

步骤：

1.先卸载所有的CocoaPods

  （1）查看 gem list cocoapods 或者 

gem list | grep cocoapods

 

或者which -a pod

或者

（2）卸载方式

brew uninstall cocoapods

或者

sudo gem uninstall cocoapods

或者

sudo rm -rf /usr/local/opt/ruby/bin/pod

或者

sudo rm -rf /usr/local/bin/pod

直到 which -a pod 为空

2.安装

sudo gem install -n /usr/local/bin cocoapods

pod setup

pod --version
