flutter 在ios模拟器上运行报错

Warning: CocoaPods minimum required version 1.6.0 or greater not installed. Skipping pod install.
  CocoaPods is used to retrieve the iOS and macOS platform side's plugin code that responds to your plugin usage on the Dart side.
  Without CocoaPods, plugins will not work on iOS or macOS.
  For more info, see https://flutter.dev/platform-plugins
To upgrade:
  sudo gem install cocoapods
  pod setup

Answer 1

你可以仔细看这里

To upgrade:
  sudo gem install cocoapods
  pod setup

其实升级cocoapod太复杂的话，你手动安装有时是不会出问题的：

$ cd ios
$ pod install
