问题是 Django 不在您的 requirements.txt 文件中。您必须在 requirements.txt 文件中包含您使用的所有模块。

要解决此问题，请更改您的 requirements.txt 文件以包含 Django（以及您使用的任何其他模块）

您的 requirements.txt 文件应如下所示（如果您没有任何其他模块）：

django
gunicorn

如果您仍然遇到相同的错误，请删除您的 Pipfile，并确保您已通过 git 暂存、提交并推送您的更改到 Heroku。

要暂存、提交和推送，请在命令行中执行以下操作（确保您位于应用程序目录中）

暂存您的更改：

git add .

提交更改：

git commit -m 'Updated requirements.txt'

要将您的更改推送到 Heroku：

git push heroku master

多亏了 ENDESSA 的评论，我才能够解决这个问题。我在 requirements.txt vs Pipfile in heroku flask webapp deployment? 中找到了解决方案。

Pipfile 和 requirements.txt 似乎有问题。当您设置 pipenv 时，它会创建 Pipfile 并忽略 requirements.txt。我的问题是我在 Pycharm 中设置了 venv 并安装了 pipenv，这会导致错误。删除 Pipfile 后，我的测试站点正常运行。

我还必须设置 heroku config:set DISABLE_COLLECTSTATIC=1，但我不确定是否还需要 heroku ps:scale web=1。

Anyhoo，非常感谢
