android-studio - 尝试运行颤振应用程序并失败说构建失败并出现异常

问题描述

我正在尝试运行一个颤振应用程序，但由于某种我无法弄清楚的原因，它不会运行。这就是我跑步时得到的。我确实将颤振/bin 浴添加到系统路径中，但这也不起作用。这发生在我重新格式化窗户之后。我所做的正是：

这是我在格式化 PC 之前第一次这样做。它奏效了。

Launching lib\main.dart on Mi 9T in debug mode...
Running Gradle task 'assembleDebug'...

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:signingConfigWriterDebug'.
> java.io.IOException: Unable to delete file: E:\codes\flutter\im_poor\build\app\intermediates\signing_config\debug\out\signing-config.json

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Get more help at https://help.gradle.org

BUILD FAILED in 5s
Finished with error: Gradle task assembleDebug failed with exit code 1

这就是颤振医生所说的：

解决方案

我通过创建一个新项目并从旧项目中复制了所有代码来解决了这个问题。
