ReactNative 踩坑记录

一、Application xxx has not been registered

　　(入口文件 --> AppRegistry.registerComponent('MyApp', () => App);    'MyApp'必须和项目名称一致

　　

二、The navigation prop is missing for this navigator

　　参考(https://stackoverflow.com/questions/53367195/invariant-violation-the-navigation-prop-is-missing-for-this-navigator)

　　解决方案：

import {createStackNavigator, createAppContainer } from 'react-navigation';
import Login from './view/login.js'
import SignUp from './view/signup.js'
const RootStack = createStackNavigator({
    Home: {
      screen: Login
    }
  });
const App = createAppContainer(RootStack);
export default App;
