Webpack导出打破了js

Question

我正在使用node，express做出反应应用程序。但突然间我得到了这个错误“Uncaught SytaxError：Unexpected Token：”

在这一行打破：

/***/ function(module, exports) {

module.exports = 
C:\Users\Dimotro\Desktop\queffect\node_modules\webpack-dev-server\client\index.js?http://localhost:3333;
/***/ },

这是我在浏览器控制台中可以看到的。 React-dev-tools完美编译，没有错误。

任何帮助表示赞赏！谢谢！
