我正在尝试首次在heroku上部署一个django应用程序，并且我因为loooooong时间而遇到同样的问题： 每次我做
heroku open
我的应用崩溃了，heroku日志说：

我的Procfile（lafusee app中的wsgi.py）：
web : gunicorn lafusee.wsgi --log-file -
如何从heroku获取更具描述性的错误消息以尝试调试我的项目？
答案 0 :(得分：1)
检查requirements.txt是否包含gunicron。
还尝试将Procfile设置为：
web : gunicorn lafusee.wsgi -b 0.0.0.0:$PORT
