assign to read only property’exports‘ of object#<Object>

assign to read only property’exports‘ of object#<Object>的解決方法

程式碼沒毛病，在webpack打包的時候，可以在js檔案中混用require和export。但是不能混用import 以及module.exports 。

因為webpack 2中不允許混用import和module.exports

解決辦法就是統一改成ES6的方式編寫即可.

lang/en.js

module.exports = {
  common: {
    login: 'Log In',

OK

export default {
  common: {
    login: 'Log In',
