控制台报错： 'ReactCurrentOwner' of undefined

解决办法：RN版本的问题。

As I mentioned, make sure you've installed the correct version of React. If you're using React Native 0.45:

yarn add react@16.0.0-alpha.12

　　　　npm install react@16.0.0-alpha.12 --save-dev

　　　　npm install --save-dev babel-preset-es2015

test:/\.jsx?$/,

        exclude:/node_modules/,

        loader:'babel-loader',

        query:{

            presets:['es2015','react']

        }

Your config is

presets: ['es2015', 'react']

but the only preset you've installed is

+-- babel-preset-es2015@6.18.0

So your answer is

npm install --save-dev babel-preset-react
