Heroku 部署成功，但未找到模块

Question

我正在将民意调查应用从 django 教程部署到 heroku。

我从 Pycharm 看到的项目具有以下分布：

我的 requirements 文件如下所示：

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

运行时为：

python-3.6.5

Procfile 为：

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

当我部署应用程序并转到浏览器时，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 声明。

我相信我的项目目录下的setting.py没有一个叫inf-shf-373的app，但它是heroku创建的随机名称。这意味着我的整个应用名称，然后 Procfile 的引用应该是 surveys（尽管有教程，我还是将投票名称更改为调查）。

有什么问题的参考吗？

编辑 回答丹尼尔罗斯曼： wsgi.py 文件位于：code/computationalMarketing/computationalMarketing/wsgi.py

额外信息： 问题是否可能是 wsgi.py 文件不在 repo 的主路径中？ django项目是第一个computationalMarketing文件夹（本项目全部集中在code文件夹），同级存在的其他文件夹有sql mods、vagrant files。

Answer 1

我终于可以解决这个问题了。

我在gunicorn 找到了参数chdir，它在django app 中建立了wsgi.py 文件的路径。

一个例子：

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