Question

我将Django项目部署到了heroku。它已成功部署，但页面显示“应用程序错误”。在heroku错误日志中是这样的。

2020-04-24T05:34:09.500250+00:00 app[web.1]: [2020-04-24 05:34:09 +0000] [4] [INFO] Using worker: sync

在Procfile中，我这样设置

web：gunicorn myWeb.wsgi --log文件-

请帮帮我。谢谢。

gunicorn似乎在错误的端口上侦听，而不是在等待哪个buildpack上侦听，因此会出现503错误。尝试将$PORT添加到您的Procfile

web: gunicorn myWeb.wsgi --log-file - --bind 0.0.0.0:$PORT
