error - webpack - Can`t resolve '../components/Hello'

ERROR in ./src/client/pages/index.tsx
Module not found: Error: Can't resolve '../components/Hello' in '/Users/liujianchuan/Github/frame/src/client/pages'
 @ ./src/client/pages/index.tsx 5:16-46

原因webpack.config.js配置错误，resolve需要指点文件类型，如下：

resolve: {
extensions: [ '.ts', '.tsx', '.js', '.json']
},
