Question

最近，在Intellij，Visual Studio等中运行我的任何flutter应用程序时，我都遇到了一个大错误。因此，我也无法执行git函数。任何帮助将不胜感激。

老实说，仅凭该错误消息很难判断出发生了什么。构建之前，intellij中是否会显示任何错误？

我唯一能想到的是：

您的flutter安装可能已损坏。您可以尝试删除并重新安装
您的构建目录可能有问题。尝试运行flutter clean，然后再重新构建
您的库未正确包含。我以为这会出现在intellij中，但也许在那儿设置的路径不同？检查项目结构->库，并查看在哪里设置路径。
（与第一个有关）您的计算机上可能有多个抖动实例。如果intellij在命令行中使用另一个时可能会导致问题。

如果您的应用恰好是开源的，或者您能够用最少的更改制作新的应用来重现错误，那么这将大大有助于诊断问题=）。

Flutter运行失败（或升级，或其他任何原因）。
