在项目':app'中没有找到任务'installDebug'--在创建项目后运行-roid

Question 1

在创建了一个react native项目后，我试图在我的安卓设备上运行它。我在终端中输入 adb devices ，我看到了我的设备。我运行了 react-native run-android 。过了一会儿， Task 'installDebug' not found in project ':app' 弹了出来。

我运行了gradlew tasks，在安装任务下没有看到installDebug。我确信我正确设置了环境变量，包括android SDK、JDK。我试着重新安装了react-native。我把sdk的位置放在android文件夹下的local.properties中。我运行了gradlew installDebug，出现了installDebug not found in root project '[app's name]'。互联网上的解决方案都没有用。
谁能帮助我解决这个问题？

Question 2


          
           
            我也面临同样的问题。
以下是对我有用的方法。
           
           
            我在Android Studio中打开了Android项目。
它可以位于YourReactNativeProjectFolder/android
           
           
            当我在Android Studio中打开这个项目时，它缺少配置。等待一段时间，让Android Studio对其进行配置并要求你更新Gradle。更新Gradle，现在你可以从Android Studio或使用命令行"
            
             npx react-native run-android
            
            "运行你的项目。
           
           
            我希望这将是有帮助的。

Question 3


          
           
            在项目根部尝试以下命令。
           
           cd android && ./gradlew assembleDebug && ./gradlew installDebug

Question 4


          
           
            
             解决办法是在Android Studio中加载/android文件夹，让它更新Gradle。之后，你就可以运行
             
              react-native run-android
             
             了。

Question 5


          
           
            
             我有同样的错误。试试下面的命令，它将显示代码的确切错误。
            
            
             cd android && ./gradlew buildRelease

Question 6


          
           
            
             for me => Mac m1
            
            
             1.- npx react-native run-android raises metro terminal(stay open metro)。
            
            
             2.- 在Android文件夹中打开proyect，并在设备上启动Emulator。(wait....)。
