It seems to be something with the requirements.txt.
Its trying to install some of the pip requirements but it fails.
I think it has something to do with distutils. I tried to upload without any requirements except 1 and it works fine (but app does not function).
The issue seems to be with flask packages and their additional packages such as itsdangerous.
here is the list of packages in the requirements.txt
click==6.7
Flask==0.12.2
Flask-SQLAlchemy==2.3.2
Flask-WTF==0.14.2
gunicorn==19.7.1
itsdangerous==0.24
Jinja2==2.10
MarkupSafe==1.0
psycopg2==2.7.4
SQLAlchemy==1.2.5
Werkzeug==0.14.1
WTForms==2.1
Does anyone know why this deployment is failing and what i can do to fix it?
Thanks
I found a better solution here, you can solve this issue using the following two commands in your command line
$ heroku plugins:install heroku-repo
$ heroku repo:purge_cache
please find the link to the solution here https://github.com/heroku/heroku-buildpack-python/issues/661#issuecomment-374183119
