【问题描述】：
我正在关注本教程 - https://medium.com/@qazi/how-to-deploy-a-django-app-to-heroku-in-2018-the-easy-way-48a528d97f9c
到目前为止，我已经：
- 构建了我的 Django 应用并在本地运行 - 完美运行
- 用内容编写了 Procfile
web: gunicorn project_name.wsgi - 将 django_heroku 导入设置
我需要安装 psycopg2 所以我跑了pip install psycopg2
但收到错误

真的觉得我在兜圈子！已重试步骤 10 次
任何帮助将不胜感激
【问题讨论】：
-
您使用的是 Mac 吗？您使用的是虚拟环境吗？
-
为什么这个标签是heroku？
-
是的，在 Mac 上运行 Mojave 和在虚拟环境中
-
这是用于部署到 Heroku，如链接教程中所述。步骤是 git push heroku master
