Question

我正在macOS 10.15.5 Catalina上运行它。我最近能够在quemu e86模拟器中运行此应用程序，但最近遇到了问题，现在出现了奇怪的Gradle错误。

我将通过说我的颤动是完全fubar'd开始的，并且无论我将路径添加到.bash_profile多少次，我都无法运行颤动医生或任何与终端内的颤动相关的操作。相信我，我浏览了许多其他文章试图弄清楚这一点，但到目前为止我还没有运气。

颤动缓存中可能存在错误。在您的终端中运行它们，看看它们是否可以帮助您：

flutter pub cache repair 
flutter clean

Android Studio Flutter失败，发生Gradle异常
