【问题描述】：

我正在尝试部署到 Heroku，但在出现此错误之前：

ModuleNotFoundError: 没有名为“django-tables2”的模块

然后我通过 pip install django-heroku 安装了 django-heroku，按照说明进行了设置。

我禁用了 heroku 的收集静态推送我的主分支，一切都很好，但是一旦我这样做：

heroku run python manage.py migrate

我明白了：

ModuleNotFoundError: No module named 'django_heroku'

完整的回溯是这样的：

Traceback (most recent call last):

    import django_heroku
ModuleNotFoundError: No module named 'django_heroku'

我的设置在顶部：

import os
import django_heroku

在最底层：

django_heroku.settings(locals())

在我的 requirements.txt 我有 django-heroku

master 分支已更新，我只能找到解决方法。

【解决方案1】：

问题是它没有添加到模块中，需要将它添加到虚拟环境中并执行 pip freeze，这样它就解决了。
