我升级到最新的flutter version 1.22.3，然后开始处理我的项目，由于构建未成功构建，我在运行项目时遇到问题。
然后我现在又切换回前一个版本的v1.17.5。
现在，我无法构建任何项目来运行，测试和部署。
我应该怎么做？

答案 0 :(得分：0)
由于豆荚过时，这可能是一个问题。请尝试下面的方法，看看它是否有效
flutter clean
cd ios
rm -rf Pods
pod install
如果上面的方法不起作用，请尝试下面的方法，基本上可以重新安装整个iOS设备
flutter clean
rm -Rf ios/Pods
rm -Rf ios/.symlinks
rm -Rf ios/Flutter/Flutter.framework
rm -Rf ios/Flutter/Flutter.podspec
rm ios/Podfile
尝试做flutter run
