react-native报错:

Navigator is deprecated and has been removed from this package. It can now be installed and imported from react-native-deprecated-custom-components

原因： 从0.44版本开始，Navigator不再从‘react-native’中引入， 同样从0.44版本开始，BackAndroid组件不在出现，而是用‘BackHandler’代替

解决办法： npm install react-native-deprecated-custom-components –save

然后在Router使用的地方：

import {Navigator} from 'react-native-deprecated-custom-components';
