TypeError: Cannot read property 'get' of undefined

I followed the video and used the express.Router(). However, when I tried to use router.get(...), I kept getting the error: 'TypeError: Cannot read property 'get' of undefined.' People from stackoverflow were saying Router.() wouldn't work for express 3.x, so I upgraded the bower.json's express dependency to 4.13.4. Nevertheless, the express dependency in package.json is 3.x version. The problem didn't get solved. Any help would be appreciated. (PS: I am use Yoeman and meanstack generator)

Bower manages client-side dependencies. Server-side dependencies the responsibility of npm, so you'll have to update the versions in package.json and run npm update.

Thanks! @Seth Kroger. I see. May I ask how to update the version of express in package.json?
