android - 我无法让我的 android 应用在 react-native 上运行

Question

我无法运行我的项目。我正在尝试修复 2 个错误，但我一无所获。

我做了这里写的一切：

https://facebook.github.io/react-native/docs/getting-started

C:\WINDOWS\system32>cd BabyMobile

C:\Windows\System32\BabyMobile>react-native run-android
info Starting JS server...
info Building and installing the app on the device (cd android && gradlew.bat app:installDebug)...
Starting a Gradle Daemon, 3 stopped Daemons could not be reused, use --status for details
> Task :app:mergeDebugResources FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:mergeDebugResources'.
> java.util.concurrent.ExecutionException: com.android.builder.internal.aapt.v2.Aapt2Exception: Android resource compilation failed
  C:\Windows\System32\BabyMobile\android\app\build\intermediates\res\merged\debug: error: directory does not exist.


* 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

Make sure you have an Android emulator running or a device connected and have
set up your Android development environment:

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

你能帮我么？

**修复：更新了 android studio，项目在普通 CMD 中初始化（不是管理员）。第二个问题是，我在运行 react-natice run-android 后打开了模拟器，所以你必须先启动模拟器！
