您将依赖项放在错误的位置。它们属于[packages]您的部分Pipfile，而不是[requires]部分。通常，您应该很少需要手动编辑您的文件Pipfile，并且您永远不应该手动修改您的Pipfile.lock. 不要向您添加东西Pipfile，而是使用 来安装它们pipenv，例如通过运行pipenv install gunicornPipenv 会自动为你更新你的Pipfile和Pipfile.lock。我建议您执行以下操作：Pipfile.lock本地删除通过运行删除旧的 virtualenvpipenv --rm移动除了python_version = "3.7"从[requires]到[packages]考虑更改所有版本，"*"以便 Pipenv 可以免费更新版本跑步pipenv installpipenv run如果您使用或从运行它，请确保应用程序在本地工作pipenv shellPipfile.lock提交Pipenv 生成的新内容部署展望未来，我强烈建议您通过运行pipenv install而不是Pipfile手动修改或使用pip. 这样做的另一个好处是确保您的本地版本与 Heroku 上使用的版本相匹配。runtime.txt哦，如果您使用的是 Pipenv，则不需要。所需的 Python 版本已在您的Pipfile.
