Question

我当时正在使用expo，但是随后需要链接第三方程序包，因此我使用Expo Kit从expo中退出。现在，当我尝试react-native run-android时，都会启动Metro bundler，但是会发生以下错误：

info Building and installing the app on the device (cd android && gradlew.bat app:installDebug)...
error Could not install the app on the device, read the error above for details.
Make sure you have an Android emulator running or a device connected and have
set up your Android development environment:

我仍然能够运行expo start，它可以在expo客户端应用程序中运行。谢谢

Answer 1

如果您只是在项目目录上expo start弹出expo工具包，然后在Android Studio或XCode中运行该项目。

Answer 2

也许您遇到的问题与我相同，没有找到setUser({})。我不知道什么时候消失了... 要解决它，您可以从另一个项目复制此文件。

在Expo Eject之后，运行Android错误：spawnSync gradlew.bat Enoent
