Android studio 尝试运行flatter应用程序，但由于出现异常而导致生成失败

我正在尝试运行一个flutter应用程序，但由于某种原因，我无法理解，它不会运行。这就是我跑步时得到的。我确实在系统路径中添加了颤振/垃圾桶，但这也不起作用。这是在我重新格式化windows之后发生的。我所做的就是：

安装Android Studio 下载颤振sdk 在Android Studio中添加了颤振插件。 这是我在格式化我的电脑之前第一次做的。它工作正常

我通过创建一个新项目并复制旧项目中的所有代码来解决这个问题。

转到文件：E:\code\flatter\im\u poor\build\app\intermediates\signing\u config\debug\out

然后选择signing-config.json文件

然后通过shift+delete删除文件

Flatter doctor-android许可证我发现这个问题与Flatter无关。这是一个巨大的问题，在我最终毁了安卓工作室并去做其他事情之前。我不确定是什么触发了它，但当我从Android Studio构建时，它未能删除旧文件——这正是您在这里看到的。尝试手动删除它们，改为从命令行运行Gradle。这是一个黑客的解决办法，但这是我唯一能做的事情
