Heroku部署成功但没有找到模块

Question

我正在将django教程中的民意调查应用程序部署到heroku。

从Pycharm看到的我的项目有如下分布：

我的要求文件显示为：

Django==2.0.5
scikit-learn==0.19.1
numpy==1.13.3
pandas==0.22.0
pymysql==0.8.1
gunicorn==19.0.0

运行时：

python-3.6.5

Procfile as：

web: gunicorn inf-shf-373.wsgi:application --log-file -

当我部署应用程序并进入浏览器时，我收到一条应用程序错误消息：

An error occurred in the application and your page could not be served. If you are the application owner, check your logs for details. 

我使用heroku logs --tail --app inf-shf-373检索日志  言。

我相信我的项目目录中的setting.py没有名为inf-shf-373的应用，但它是由heroku创建的随机名称。这意味着我的整个应用名称，然后Procfile的引用应为surveys（尽管有教程，我将民意调查名称更改为调查）。

有关问题的任何参考？

修改 回答DanielRoseman： wsgi.py文件位于：code / computationalMarketing / computationalMarketing / wsgi.py

额外信息： 是否有可能问题是wsgi.py文件不在repo的主路径中？ django项目是第一个computeMarketing文件夹（这个项目全部聚集在代码文件夹中），同一级别存在的其他文件夹是sql mods和vagrant文​​件。

Answer 1

最后我已经能够解决这个问题。

我在chdir处找到了参数gunicorn，在django应用程序中稳定了wsgi.py文件的路径。

一个例子：

web: gunicorn --chdir code/computationalMarketing computationalMarketing.wsgi --log-file -
