问题
I tried a lot but not able to find the reason for this. Need help. Following is what I am writing after deploying my first node app in Heroku and my DB is at MongoLab
heroku ps:scale worker=1
It is giving me following error.
! No such type as worker.
My Procfile look like this,
web: node server/server.js
Here is my log file look like

回答1:
The command you are running is trying to scale up the number of worker processes to 1 but you have only declared a web process type. If you are trying to scale up the number of web processes you would use heroku ps:scale web=1. If you are trying to make a new worker process you need to define a worker in the procfile and push to Heroku before trying to scale it (worker: node server/worker.js). The Heroku documentation on process types should be of some help as well.
