推荐答案

要确保为Android正确设置了环境，请转至react-native项目的根目录.在Android Studio IDE中打开android项目(文件夹).

To make sure your environment is setup properly for android, go to the root of your react-native project. Open the android project(folder) in the Android Studio IDE.

与环境有关的所有错误都会显示出来，并且会自动启动Gradle Daemon来为您同步和配置构建.完成后，关闭Android Studio，然后返回命令行并运行:react-native run-android

All errors with your environment will show up, and that will automatically start the Gradle Daemon to sync and configure the build for you. Once it finished, close the Android Studio and come back to command-line and run: react-native run-android

这很好.
