Worker 无法启动

Question

我正在尝试在 Heroku 上部署我的 Django 项目，但是出了点问题，我无法找出发生了什么，以及如何解决这个问题。我在其他帖子中看到问题可能与 Gunicorn 有关，但我无法解决。

Answer 1

你的 gunicorn start 命令看起来很奇怪：

Starting process with command `gunicorn mysite.wsgi --log-file -`

该命令应指定模块名和变量名，用冒号分隔，如下所示：

gunicorn mysite.wsgi:application

Answer 2

解决方案：

问题在于我的 Procfile 文件的位置：它必须与 manage.py 位于同一路径上。就是这样！
