我正在尝试使用heroku-django-template将我现有的Django项目推送到Heroku，作为修改我的django项目的参考。
我的解释器是Python 2.7.14，我没有使用虚拟环境。
但经过一整天的尝试，我只是反复得到这个错误：
remote: -----> App not compatible with buildpack: https://codon-buildpacks.s3.amazonaws.com/buildpacks/heroku/python.tgz
remote: More info:https://devcenter.heroku.com/articles/buildpacks#detection-failure
remote:
remote: ! Push failed
remote: Verifying deploy...
remote:
remote: ! Push rejected to py-mosaic-image.
remote:
To https://git.heroku.com/py-mosaic-image.git
! [remote rejected] master -> master (pre-receive hook declined)
这是我的字典：
-- .git/
-- my-project/
---- some-app-dir/
---- some-app-dir/
---- my-project/
---- __init__.py
---- .env
---- db.sqlite3
---- manage.py
---- Pipfile
---- Pipfile.lock
---- Procfile
---- requirements.txt
---- runtime.txt
这里有一些代码（很多是由heroku-django-template生成的）

有谁知道这有什么问题？我搜索并尝试但都失败了：（
