Python heroku -app not compatible with buildpack

Question

I read all the previous posts about it but still couldn't correct it. I added requirements.txt and Procfile in the directory in my computer created by Heroku. Procfile reads "web: python Chat Server.py". Also added runtime.txt in the same directory that reads "python-3.6.2".However, it keeps giving the same error again in the command prompt. How can I solve this? This is the entire error message:

"C:\\Users\\asus\\chat_server>git push heroku master Counting objects: 6, done. Delta compression using up to 4 threads. Compressing objects: 100% (4/4), done. Writing objects: 100% (6/6), 1.14 KiB | 585.00 KiB/s, done.

Answer 1

Anyone reading this: you'll need two files:

First file: requirements.txt containing something like: gunicorn==19.7.1 or whatever the results of pip freeze > requirements.txt are.

Second file: Procfile containing something like: web: gunicorn app:app or potentially blank. Note that app:app in this example is a reference to your python filename. It means that every time a web process is declared, and a dyno of this type is started, also run the command gunicorn app:app to start your web server.

Then git add . and git commit -m "added Procfile and requirements.txt" .

Then run git push heroku master to push from your local master branch to the heroku remote.

除了JaredH的答案之外，在运行git push heroku master之前，请确保您当前的分支是git push heroku master 。
