Packaged errors when using webpack

[keifergu]

Error information :

ERROR in ./~/.0.0.7@jsqrcode/src/qrcode.js
Module not found: Error: Can't resolve 'canvas' in '/mnt/c/Users/Keifer.Gu/Desktop/Document/WorkSpace/test/node_modules/.0.0.7@jsqrcode/src

Version info:

• webpack ; 2.4.1
• jsqrcode: 0.0.7
• OS: windows 10

What I did:

I use webpack to build JavaScript files, building environment is node, but the operating environment is the browser. So in the packaging of the time, jsqrcode wrong to judge the environment.
