Going by the original book to Deploy on Heroku. Followed instructions step by step. When I try to push the code to Heroku I keep hitting this issue:
Push rejected, failed to detect set buildpack heroku/python
remote: More info: https://devcenter.heroku.com/articles/buildpacks#detection-failure
I have my requirements.txt and Procfile set up and in the main folder.
Any suggestions?
