ModuleNotFoundError：“沒有命名的模塊<mymodule> "，從 Django 部署到 Heroku 時</mymodule>

Question

將我的 Django 應用程序部署到 Heroku 時，我收到一個 ModuleNotFoundError ，指出“沒有名為 'RealisticEstate' 的模塊”。 RealisticEstate 是我的 Django 項目的名稱。 該程序構建沒有問題，但是當我嘗試部署時，出現以下錯誤：

9:35:45 PM web.1 |  ModuleNotFoundError: No module named 'RealisticEstate'

我的Procfile如下：

web: gunicorn RealisticEstate.wsgi

我的 Heroku 項目被命名為“realisticestate”，但是當我嘗試將我的 Procfile 更改為：

web: gunicorn realisticestate.wsgi

它會引發相同的錯誤。

這是項目結構：

RealisticEstate
|___config
|   |___static
|   |   |___admin
|   |       |___css     
|   |       |___font

任何幫助將不勝感激

Answer 1

只有 git 根目錄 ( RealisticEstate ) 中的內容將被推送到 Heroku，而不是目錄本身。 您的 wsgi 文件是config/wsgi.py因此您應該使用：

web: gunicorn config.wsgi

Answer 2

確實，您需要將 project_name 放在您的 Procfile 中，並且因為始終包含所有文件夾的文件夾與wsgi.py 存在的文件夾具有相同的名稱。您的 Procfile應該指向，但在您的情況下，您命名它配置所以它應該是：

web: gunicorn config.wsgi 

我個人是這樣添加的：

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