I am trying to deploy a Django app via Heroku for the first time.
When I run git push heroku master it returns this error:
remote: -----> Building on the Heroku-20 stack

Following similar problems on SO I believe I have my file structure correctly configured - with git deployed from same place as my Procfile etc. I also have a requirements.txt file which I believe tells Heroku it's a python app - so I can't figure out why the buildpack isn't working.
Based on comments and feedback I moved all folders into root directory but receive the same error.
Heroku only looks for your Procfile, requirements.txt, and runtime.txt in the root directory of your project. Move them up a level so they're beside your .gitattributes.
That should let Heroku detect that this is a Python project and get past the current error.
But your project still won't run. Out of the box, Heroku will expect your Django project to also be in the root directory of your repository. You can probably get it to work from a subdirectory by playing around with the DJANGO_SETTINGS_MODULE environment variable and / or PYTHONPATH, but the easiest solution is to move your entire project up a directory.
I suggest you move everything from anybody/anybody1/ to anybody/, then delete the now empty anybody/anybody1/ directory.
Then commit, and redeploy.

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'm trying to deploy a Django app to Heroku, encounter the identical problem as python - Collectstatic error while deploying Django app to Heroku - Stack Overflow
it starts to build, download and installs everything, but that's what I get when it comes to collecting static files:

! [remote rejected] master -> master (pre-receive hook declined)
error: failed to push some refs to 'https://git.heroku.com/fierce-cove-94300.git'
I tried all its answers, but not helps.
Additional I tried Django and Static Assets | Heroku Dev Center to configure the setting and install whitenoise and commit changes.
The problem is not solved.
Disable auto collectstatic:
heroku config:set DISABLE_COLLECTSTATIC=1
Then push your project to heroku. After the deploy is done, manually collectstatic as below:
heroku run python manage.py collectstatic
If you still get errors, your static files config is probably the reason. Try making it simple, remove whitenoise and use a s3 bucket for example.
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.

Does your local requirements.txt match requirements.txt from master branch?
I had the same problem and finaly I realized that my master branch had that pkg-resources line in requirements.txt while my local copy hadn't. I deleted that line from requirements.txt, did git commit, git push and next time I tried to push my app to heroku I succeed.

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.
