如果您使用的是 django-heroku 包，那么您必须将其添加到您的 settings.py

将以下导入语句添加到 settings.py 的顶部：

import django_heroku

然后将以下内容添加到 settings.py 的底部：

# Activate Django-Heroku.
django_heroku.settings(locals())

查看官方文档。 https://devcenter.heroku.com/articles/django-app-configuration#settings-py-changes

您是否在项目文件夹中创建了 Procfile 文件？ 如果您使用的是 Windows PS，您可以输入 terminal:

echo web: gunicorn <<YOUR_PROJECT>>.wsgi --log-file - > Procfile

另一种可能的解决方案是使用 Postgres 而不是 MySQL：

在settings.py中：

DATABASES = {
    'default': dj_database_url.config()
}

在requirements.txt中：

psycopg2-binary==2.8.6
