React-native 问题 - 任务 ':app:compileDebugJavaWithJavac'

如何解决React-native 问题 - 任务 ':app:compileDebugJavaWithJavac'

所以我正在与我的团队合作进行项目。起初我有两个问题，你可以在这个页面上找到：

React-native problem with launching the app

我不知道这两个问题是否消失了，或者我只是在它们上面放了另一个问题，但它就在这里。如果您有任何线索，请写信给我，我一直在努力解决这个问题。起初，当我将我的分支与其他队友合并时，一切都很好，但是在第二次合并后发生了这种情况：

解决方法

你安装 android-platform-tools 了吗？

如果已经连接，请检查您的设备是否已连接运行：

$ adb devices

它会显示您的设备 ID

如果您的设备已连接，但仍然出现错误，请尝试以下操作：

$ adb -s 反向 tcp:8081 tcp:8081

然后再次运行。如果仍然出错，试试这个：

$ npx react-native run-android --deviceId

,

我认为您在升级版本或安装新软件包时犯了一些错误。

请检查这个。
