What is the reason for “Procfile declares types -> (none)” in Heroku?

Question

I am trying to deploy a test app to Heroku --stack cedar but every time I do my Procfile is being ignored.

It should be saying this:

Procfile declare         


        

Answer 1

I have sth to say about "Procfile declares types -> (none)" error.

One thing we should pay attention to is the hidden extension of "Procfile" file. I thought my command in "Procfile" was correct but I kept receiving this error. After half an hour I found that "Procfile" has the extension ".txt" but was hidden by the default setting of my macOS. After removing the extension, everything works fine!

I'm adding to Pascal Lindelauf answer - make sure your file name is "Procfile" (with a capital P) and not "procfile" (that was the case with me just now) good luck!

Answer 3

I had this problem deploying a Django app to Heroku.

• the git repository has to be initialised in the Django project root folder (where manage.py lives)
• this is also where the Procfile needs to sit

File structure:

Documents/
|---djangoprojectname/
|   |---djangoprojectname/
|   |   |---__init__.py
|   |   |---settings.py
|   |   |---urls.py
|   |   |---wsgi.py
|   |---djangoappname/
|   |---.git
|   |---manage.py
|   |---Procfile

The Procfile should look like this as per the docs:

web: gunicorn djangoprojectname.wsgi

Did you remember to commit your Procfile to git? I've forgotten to do this commit, done a git push heroku master, and seen the (none) message stated above.

If you've forgotten, then commit your Procfile and perform git push heroku master again.

I was getting the same problem, and tried everything posted here. I was getting:

Procfile declares types -> (none)

Instead of Procfile declares types -> web. My fix was to change in the regedit to 0 (tutorial here https://www.thewindowsclub.com/show-file-extensions-in-windows) and then deleting the .txt in the end of Procfile (So It was just a file with no extension). After that my problem was solved! You can check if you have solved doing the following commands in the cmd:

heroku ps 

Should display something like:

=== web (Free): gunicorn app:app (1)

Or the git push:

git push heroku master

And that should display:

Procfile declares types -> web
