I'm trying to deploy a large django project to heroku. I installed Heroku CLI, logged in, created an app and ran:
git push heroku master
I have a Pipfile and requirements.txt already set up. I added a runtime.txt to specify that I need python 2.7. This is also in the Pipfile. This is what I get from pushing to heroku:

I'm not sure why it tries to install python 3, and it also doesn't like my Pipfile.lock file. I've tried deleting it and generating it again with pipenv install but that didn't change anything.
Make sure you have initialised your environment in Python 2.X with pipenv --two, then - given your code runs locally and all dependencies are specified in your Pipfile - run pipenv install and commit all changes including the Pipfile.lock to your local git repo (git add * && git commit -m "your message"). Finally push to heroku. Hope it now builds correctly.

Deployed some new code into an app on Heroku and now showing the following message: No module named 'requests' . The app was working fine before, so this has to be something I changed.
Before I show the code there is 2 things that I noticed: my Procfile & requirements files are not visible from Visual Studio (can be seen from Sublime Text Editor). Recently started using VS and only noticed it now. Not sure if this is of importance here.
I am not sure where the error is coming from so I left below traceback, Procfile and requirements.txt files.
Let me know if I need to add something else.

You have to add requests in Requirements.txt like this :
requests==2.28.1
Install request by running the below command
pip install requests
Then update your Requirements.txt just run
pip freeze > Requirements.txt
This will add all libraries that you have used in the project including the newly installed.
So I try to make a very simple test app to run with Heroku. Its my 3rd attempt from complete scratch. I have a single python file with very minimal content
from flask import Flask
app = Flask(__name__)
#app.route("/")
def test():
return "test"
if __name__ == '__main__':
app.run()
the file is named test.py, my directory also includes Procfile
web: gunicorn app:test
and requirments.txt
click==7.1.2
Flask==1.1.2
gunicorn==20.1.0
itsdangerous==1.1.0
Jinja2==2.11.3
MarkupSafe==1.1.1
Werkzeug==1.0.1
to top it off I have gitignore to ensure IDE files do not interfere,
.idea
.Heroku.iml
and runtime.txt
python-3.6.0
I then try to create an app using
heroku create <appname>
I then use second URL it returns in the command
git remote add heroku <url>
. Afterwards I do
git add .
git commit -m "some message"
git push heroku main
and get the following error.
To https://git.heroku.com/forgotten-fox.git
! [remote rejected] master -> master (pre-receive hook declined)
error: failed to push some refs to 'https://git.heroku.com/forgotten-fox.git'
I then try to do it using
git push heroku master
instead but no changes occur.
I also try to force it to use python build pack with
heroku buildpack:set heroku/python --app <appname>
as above the error it states that
Building on the Heroku-20 stack
remote: -----> Using buildpack: heroku/python
remote: -----> App not compatible with buildpack: https://buildpack-registry.s3.amazonaws.com/buildpacks/heroku/python.tgz
remote: More info: https://devcenter.heroku.com/articles/buildpacks#detection-failure
I don't know how to use git mostly, but my friend advised me to create remote repository and attach it to Heroku but I was not able to find how to do the attachment.
If anyone knows what causes that and / or how to solve it i would really appreciate if you share the knowledge.
Update:
Thanks for pointing out wrong name for requirements file, I've renamed it. I`ve also changed my Procfile to
web: gunicorn test:app
.
Sadly it doesn't resolve the issue (yes I did commit and push the changes made).
Here is the error messages:

Update
Ok, sorry everyone, I'm generally retarded. I missed the obvious part of error about build back, here it states the final fix I needed for my app to work.
the issue is that you have to use
web: gunicorn test:app
instead of
web: gunicorn app:test
the correct format is
gunicorn <filename>:<app object>
When I deploy app in heroku show me this error
remote: ERROR: Could not find a version that satisfies the requirement apturl==0.5.2 (from -r /tmp/build_16067d5dbf345d8d906970e4d4f44d30/requirements.txt
I searched on internet to finding the solution of that problem but can't successfully find this.
So I show you what steps I had do for deploy app in heroku
I typed in terminal
heroku login
pip3 freeze
pip3 freeze > requirements.txt
Then for instaling gunicorn type in terminal
pip3 install gunicorn
Then make a file in root directory write name is Procifle in which I write
web: gunicorn django_project.wsgi
Then my heroku blog name
heroku git:remote -a naqviblog
I also show you my requirements.txt file

That's a lot of packages. Are you sure your project requires them all?
You added the python-3.7 tag but Heroku says it is using python 3.6. Ensure that both developing and production environment match.
apturl does not exist on PyPI https://pypi.org/. When you run python -m pip install packagename you search for it on PyPI. It does not exist on there. You may have installed it through apt, setup.py, wheels, etc.
I'm attempting to upgrade several Django apps on Heroku to Cedar-14 using the following commands from Heroku's documentation:
➜ project-name git:(master) ✗ heroku stack:set cedar-14
Stack set. Next release on project-name will use cedar-14.
Run `git push heroku master` to create a new release on cedar-14.
➜ project-name git:(master) ✗ git commit --allow-empty -m "Upgrading to Cedar-14"

(The answer to this actually comes form user Kenneth Reitz, which was answered on the Heroku support channel. Thanks!)
Since this didn't appear to be a problem related to the application code, the Heroku team suggested I purge the build cache, using this tool: https://github.com/heroku/heroku-repo
The commands I ran were:
heroku plugins:install heroku-repo
heroku repo:purge_cache -a project-name
That seemed to do the trick!

I created a requirements.txt file, as advised in Heroku push rejected, no Cedar-supported app detected and I then typed in pip install -r requirements.txt before typing in git push heroku master again but I got the same output and so I need to know how to let Heroku know requirements.txt exists so I don't get this same error again.
I typed in git commit -m 'another commit' and I got this output:
Your branch is up-to-date with 'django/master'.
Untracked files:
procfile
requirements.txt
I then typed in these commands:
git add procfile
git add requirements.txt
I typed in git commit -m 'another commit' and then git push heroku master, which worked.
I'm not really sure, but maybe you miss to add a [Procfile].(https://devcenter.heroku.com/articles/procfile) This file is neccesary to declare which server/process is going to run the dyno.
