Xcode 11.2，Catalina和Flutter v1.9.1 + hotfix.6

• 问答

升级后，我以前使用Vcode的Flutter项目无法再构建，并且出现如下大量错误。我尝试过：

  1. 删除podfile.lock
  2. pod缓存清理--all
  3. rm -rf〜/ library / Caches / Cocoapods
  4. rm -rf〜/ library / Developer / Xcode / DerivedData / *
  5. rm -rf豆荚
  6. pod解体
  7. pod设置
  8. pod安装

您是否尝试过更新ios文件夹上的pod？

pod update

然后再次运行您的项目。

,

您可以尝试在应用程序的根文件夹中调用flutter clean。

,

您的项目已损坏。我通过创建新的Flutter项目，然后在其中复制源代码，.yaml文件，lib文件夹和assets来解决该问题，然后重新构建项目。

flutterios
