Heroku - Flask - Bcrypt error
Add cffi or cryptography in requirements.txt .That solved the problem in my case.
I am attempting to deploy a flask app on Heroku and it always errors at the same place. GCC fails to install and compile the Bcrypt module so I removed it from my requirements.txt (it is not used in the app). When I view the requrements.txt file, there is no mention of Bcrypt but when I push to heroku, it still tries to install it. I have committed the most recent version of requirements.txt to Git. Any help would be greatly appreciated.
