webpack热刷新后页面出错

Question

原来HMR可以正常运行,引入socket.io后开始出现警告，还能实现热刷新，但页面其他地方开始报错

chrome的警告信息：

[HMR] bundle has warnings:
[HMR] ./visual-workbranch/script/utils/socket.io-1.4.5.js
Critical dependencies:
26:88-96 This seems to be a pre-built javascript file. 
Though this is possible, it's not recommended. 
Try to require the original source to get better results.
 @ ./visual-workbranch/script/utils/socket.io-1.4.5.js 26:88-96

服务端的警告信息：

WARNING in ./visual-workbranch/script/utils/socket.io-1.4.5.js
Critical dependencies:
26:88-96 This seems to be a pre-built javascript file.

This seems to be a pre-built javascript file. 该怎么处理？
