在最新检查期间未能捕获任务“：app：compileFlutterBuildDebugArm”属性“outputDirectory”的输出文件指纹

Question

我尝试调试我的应用程序，但它告诉我：

What went wrong:
Failed to capture fingerprint of output files for task ':app:compileFlutterBuildDebugArm' property 'outputDirectory' during up-to-date check.
Could not read path 'C:\Users\(myuser)\Documents\pop_up\build\app\intermediates\flutter\debug\android-arm\flutter_assets\fonts'

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.

BUILD FAILED in 1s
Gradle task assembleDebug failed with exit code 1
Exited (sigterm)

命令

Answer 1

您是否在某个地方删除了一些文件，比如说您的资产文件夹以及您在 pubspec.yaml 上也引用的此类文件？如果是这就是应用程序未构建的原因，请尝试删除对已删除文件的引用（那些在您的应用程序的 pubspec.yaml 中不存在的文件），然后再次运行项目以查看它是否成功构建。

Answer 2

这似乎是某种文件锁定问题...当尝试打开输出中指定的路径时，Windows 资源管理器实际上返回“访问被拒绝”，因此我无法访问文件夹并且无法更改安全。 重启后文件夹就可以访问了。

什么对我有用（目前仅按确切顺序）：

1. 在 VS Code 中打开另一个文件夹（如果您正在使用它）。如果整个过程都不​​起作用，请重新启动计算机
2. “flutter clean”命令
3. 调试
