Heroku : Fails to deploy - No module named 'pip.req'

[processor286]

Using the deploy button on the README.md page, I see:

ModuleNotFoundError: No module named 'pip.req'

Can't see how to get past this with the Heroku deployment.

It seems that for other ( https://github.com/stevenleeg/geemusic/issues/282 ) deployments, this can be worked around by changing the pip version in use to 9.x , but I don't see how I can do this with the Heroku deployment.

Someone else ( https://github.com/stevenleeg/geemusic/issues/299 ) did get it to deploy apparently though.

Okay so this is a dependency from flask-ask, which has been fixed, but never released to PyPi. Seems hard to know what to do for the best here.
