Question

我是新手，对本地人有反应。我开始了一个新项目，并遵循了所有步骤。我以前有Android Studio，然后用它启动了模拟器。运行npx react-native run-android命令后，出现此错误。

**FAILURE: Build failed with an exception.
* What went wrong:
Task 'installDebug' not found in project ':app'.
* 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.
* Get more help at https://help.gradle.org
BUILD FAILED in 34s

然后我运行了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

您能帮我吗？

Answer 1

如here所述，您可以尝试在项目的根文件夹上运行以下命令：

cd android && ./gradlew installDevDebug && cd .. && react-native run-android --variant=DevDebug

此后，您的项目应成功在Android上运行。

否则，请使用android studio一次打开您的项目，然后使用react-native run-android

重新编译

即使在此之后所有项目都无法正常工作，请确保PATH变量上已经有ANDROID_HOME变量

无法使用Android模拟器打开React Native项目
