我正在尝试在Heroku上部署Python Flask app。当我拥有Pipfile时，我曾经部署得很好，但是Heroku的buildpack优先于pip安装requirements.txt，所以我考虑删除Pipfile和Pipfile.lock，因为即使不使用虚拟环境也似乎更简单。这个项目。
但是，这在推送到存储库时引发了另一个问题：

确实是在Pipfile中指定的：
[[source]]
url = "https://pypi.python.org/simple"
[packages]
requests = { extras = ['socks'] }
[requires]
python_full_version = "3.6.5"
但是，即使在python-3.6.6文件中写入requirements.txt行，现在也会发生这种情况。
我应该退回Pipfile吗？
