react-native编译项目报错

Question

react-native 编译项目报错。手机是白屏状态，

BUNDLE ./index.js

ERROR ReferenceError: Can't find variable: document
ERROR Invariant Violation: Module AppRegistry is not a registered callable module (calling runApplication). A frequent cause of the error is that the application entry file path is incorrect.
This can also happen when the JS bundle is corrupt or there is an early initialization error when loading React Native.

尝试过卸载node_modules但是没用，
这是什么问题，

错误的常见原因是应用程序入口文件路径不正确。
