报错信息为UnableToResolveError: Unable to resolve module react/lib/ReactComponentWithPureRenderMixin from /node_modules/react-navigation/src/views/Header.js
原因： Header.js中引入了ReactComponentWithPureRenderMixin，但后面未发现对这个引入的使用。
1.办法一：
"react": "16.0.0-alpha.3", "react-native": "0.43.2", "react-navigation": "git+[https://github.com/react-community/react-navigation.git#7edd9a7](https://github.com/react-community/react-navigation.git#7edd9a7)"
把package.json改成上面的版本 把node-modules 文件夹删除，再npm install .
2.办法二：
将header.js第12行的代码
import ReactComponentWithPureRenderMixin from 'react/lib/ReactComponentWithPureRenderMixin';
删除
详见 https://github.com/react-community/react-navigation/issues/923
