【问题描述】：

我无法使用代码 react-native run-android 运行 react-native 项目。我收到以下错误

info Starting JS server...
info Building and installing the app on the device (cd android && ./gradlew app:installDebug)...

FAILURE: Build failed with an exception.

* What went wrong:
Could not determine the dependencies of task ':app:compileDebugJavaWithJavac'.
> Could not create service of type AnnotationProcessorDetector using JavaGradleScopeServices.createAnnotationProcessorDetector().

* 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 1s
error Could not install the app on the device, read the error above for details.
Make sure you have an Android emulator running or a device connected and have
set up your Android development environment:

error Command failed: ./gradlew app:installDebug. Run CLI with --verbose flag for more details.

但如果我以 root `sudo react-native run-andoid' 运行它，它就会运行。

如何让项目在没有 root 权限的情况下运行？？

【解决方案1】：

我在阅读 Medium 的 post 时发现，当您在安装 react native 和 realated 工具时遇到权限问题时，您必须明确授予每个文件夹的权限，这样您就可以在不使用 sudo 的情况下运行应用程序。否则sudo安装的文件只能sudo运行。

使用以下命令授予当前用户对该特定文件夹的访问权限

sudo chown -R $(whoami) ~/Documents/Myapplicationfolder
