之前项目在VScode里运行时没有任何问题，但是隔天再次打开时候报错了，报错如下
> Task :app:processDebugResources FAILED
FAILURE: Build failed with an exception.
* What went wrong:
Failed to capture snapshot of output files for task ':app:processDebugResources' property 'sourceOutputDir' during up-to-date check.
> Could not read path 'D:\ReactNativeProject\MyApp\android\app\build\generated\not_namespaced_r_class_sources\debug\processDebugResources\r\com\facebook\imagepipeline\backends'.
* 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
经过查询后知道如何解决，按照下面的方法就可解决
//在项目的路径下输入
PS D:\ReactNativeProject\MyApp> cd android
PS D:\ReactNativeProject\MyApp\android> ./gradlew clean
//等待加载完后，回到上一层目录，执行react-native run-android。
PS D:\ReactNativeProject\MyApp\android> cd ..
PS D:\ReactNativeProject\MyApp> react-native run-android
问题解决
