Answer 1

I am not sure if your question is still on, but I'm digging into heroku right now, too and I have a solution for you. The fcntl module is a standard library available... on Linux only! You won't find it under Windows environment, which you are apparently using (hint: Notepad mentioned ;)

But no worries, just follow the official tutorial's previous lesson and invoke the local heroku server like:

heroku local web -f Procfile.windows

This should start your local heroku server no problem, under: http://localhost:5000

Hope that helps!

P.S. Don't run views.py on its own like that. The tutorial strictly says to do it under the virtual environment, then it works, like planned.

1. (python-getting-started) Ja ~/python-getting-started (master) pipenv install requests
