【问题描述】：

当我尝试在 heroku 上运行我的应用程序时出现此错误。不知道是什么原因造成的

ModuleNotFoundError：没有名为“deploytest.settings”的模块 2020-05-15T21:02:25.372974+00:00 app[web.1]: [2020-05-15 21:02:25 +0000] [10] [INFO] 工人退出（pid：10） 2020-05-15T21:02:25.542793+00:00 app[web.1]: [2020-05-15 21:02:25 +0000] [4] [INFO] 关闭：主 2020-05-15T21:02:25.542795+00:00 app[web.1]: [2020-05-15 21:02:25 +0000] [4] [INFO] 原因：Worker 无法启动。

过程文件

web: gunicorn deploytest.deploytest.wsgi

当我的 procfile 是时，我得到同样的错误

web: gunicorn deploytest.wsgi

wsgi.py:

django_heroku.settings(locals())

我的文件结构是您对任何典型 django 项目的期望。所以 settings.py 和 wsgi.py 都在 deploytest/deploytest 目录中。我不知道是什么原因造成的。

更新：

将我的 git 放入 deploytest/ 确实有帮助。我让网站正常工作了。

【问题讨论】：

标签： django heroku

【解决方案1】：

尝试以这样一种方式部署deploytest/，以便您也可以在 root 中看到其他应用程序。我的意思是不要上传这个文件夹

部署测试/部署测试

如果你不明白我的意思问。

那就用这个Procfile

web: gunicorn deploytest.wsgi --log-file -

【讨论】：

【解决方案2】：

我可以通过在我的 Procfile 中使用 gunicorn 的 --chdir 标志来解决这个问题。所以在这种情况下，我相信以下方法会起作用：web: gunicorn --chdir deploytest deploytest.wsgi
