为什么独立的react-native应用程序不起作用，但在Expo Client上运行良好？怎么解决？

Question

我正在构建一个反应本机应用程序，在expo客户端上工作正常。但我得到：'未捕获错误：在启动画面后在日志中调用AppRegistry.runApplication'时出错。

我添加了AppRegistry.registerComponent（'main'，（）=> App），这通过Expo客户端工作。我是通过expo build：android创建SDK的。

{
  "main": "App.js",
  "scripts": {
    "start": "expo start",
    "android": "expo start --android",
    "ios": "expo start --ios",
    "eject": "expo eject",
    "test": "node ./node_modules/jest/bin/jest.js --watchAll"
  },
  "jest": {
    "preset": "jest-expo"
  },
  "dependencies": {
    "@expo/samples": "2.1.1",
    "expo": "^32.0.0",
    "react": "16.5.0",
    "react-native": "https://github.com/expo/react-native/archive/sdk-32.0.0.tar.gz",
    "react-native-elements": "^1.1.0",
    "react-native-material-cards": "^1.0.9",
    "react-native-shadow": "^1.2.2",
    "react-navigation": "^3.0.9",
    "typescript": "^3.4.1"
  },
  "devDependencies": {
    "babel-preset-expo": "^5.0.0",
    "jest-expo": "^32.0.0"
  },
  "private": true
}

当您输入'expo init appname'时，您输入的名称是'main'吗？

AppRegistry.registerComponent('AppName', () => componentName)

如果没有，请参阅this link.
