[467] Error: Cannot find module 'vue' on Heroku;

Hello there. I've created a new app using starter template, it's almost empty, works fine on local machine and gives me this error on heroku: <img width="901" alt="screen shot 2017-03-28 at 11 23 02 pm" src="https://cloud.githubusercontent.com/assets/16022609/24425613/7883bbde-140d-11e7-958d-5672d4359466.png"> I have another nuxt app there, with older nuxt version and it works as intended, so I don't know what it could be.

Adding package.json, maybe it helps.
