我是 React Native 的新手。我开始了一个新项目并遵循了所有步骤。我之前有 Android Studio，我用它启动了模拟器。运行 npx react-native run-android 命令后，出现此错误。
**FAILURE: Build failed with an exception.
* What went wrong:

* Try:
Run gradlew tasks to get a list of available tasks. 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.

然后我运行 abd -d 命令，我明白了。
Android Debug Bridge version 1.0.41
Version 29.0.6-6198805
Installed as C:\Users\User\AppData\Local\Android\Sdk\platform-tools\adb.exe
你能帮我解决这个问题吗？
最佳答案
如前所述here ，你可以尝试在项目的根文件夹中运行以下命令:
cd android && ./gradlew installDevDebug && cd .. && react-native run-android --variant=DevDebug
在此之后，您的项目应该可以在您的 Android 上成功运行。
如果没有，用android studio打开你的项目一次，然后用react-native run-android重新编译
如果即使在这之后您的所有项目都无法正常工作，请确保您的 PATH 变量中已经有 ANDROID_HOME 变量
