问题背景：

升级 React Native 0.55.4 -->  React Native 0.56.0 后，运行报错：Cannot read property 'bindings' of null

babel-preset-react-native版本过低造成，React Native 0.56.0 需要 [email protected] 版本

解决方案：

1. [root@node1 demoProject] yarn remove babel-preset-react-native
2. [root@node1 demoProject] yarn add [email protected]
