升级 Flutter 版本后运行 pod install 时出现 Flutter 错误

Question

将flutter版本升级到最新的Flutter 2.2.1后，在ios模拟器上运行app，运行pod install报错

我尝试通过执行以下命令来清理 Pod，但没有解决问题

flutter clean
flutter pub get
rm -Rf ios/Pods
rm -Rf ios/.symlinks
rm -Rf ios/Flutter/Flutter.framework
rm -Rf ios/Flutter/Flutter.podspec
rm ios/Podfile

最后

flutter run

Answer 1

试试这个： 转到ios文件夹并运行

pod install --repo-update 

Answer 2

以下步骤对我有用：

1. 运行flutter clean
2. 运行flutter pub get
3. 运行flutter pub upgrade
4. 删除项目ios文件夹内的Podfile、Podfile.lock和Pods文件夹
5. 运行flutter clean
6. 运行flutter run
