commonJS引入报错

[KaiOrange]

代码：

var html5ImgCompress = require('/dist/html5ImgCompress.min.js');

错误信息：

TypeError: Cannot set property 'html5ImgCompress' of undefined
    at index.js:506
    at Module.<anonymous> (index.js:507)
    at Module../assets/js/upload_img/html5ImgCompress.min.js (index.js:666)
    at __webpack_require__ (runtime.js:788)
    at fn (runtime.js:151)

建议搞一个npm安装包来引入，这样方便一些。
