Django Heroku部署带来应用程序错误

在通过Heroku部署了我的django应用程序后，我注意到它在某种程度上能够成功部署，但在访问实际网站时，它给了我一个“应用程序错误”。我不太确定这里发生了什么

运行heroku日志后，我收到以下消息：

是否可能找不到gunicorn或settings.py不正确？

是

requirements.txt中的
gunicorn
？是的，我重新定义了pip安装gunicorn，但是，它已经在那里了。你能发布你的requirements.txt和你的procffile吗？argon2 cffi==18.1.0 bcrypt==3.1.4 certifi==2018.4.16 cffi==1.11.5 Django==2.0.5 Django-bootstrap3==10.0.1 Django支架==1.13.0 Faker==0.8.15 gunicorn==19.9.0 misaka==2.1.0枕头==5.0.0 pycparser==2.18 Pythong-Datez==2.7.4.11.0text unidecode==1.2'Procfile:web:gunicorn socialnet.wsgi
