ModuleNotFoundError: No module named 'my_app’, app already in INSTALLED_APPS

Question

我正在尝试通过 Heroku 部署我的 Django 应用程序，但在运行具有 gunicorn wsgi 路径的生产环境之后我得到了一个 ModuleNotFound error。我的应用程序包含在 settings.py 中，并且在开发环境中运行良好。但是现在我收到部署错误。我的项目结构有问题，因此 Procfile 与 manage.py 不在同一个目录中，我相信这可能是问题所在。非常感谢任何提示或帮助。

目录结构

 >FINALPROJECT(root)
    > .vscode
    > project5
        > brainSkills
           > migrations
           > static
           > templates
           apps.py
           models.py
           urls.py
           views.py
        > project5
           _init_.py
           settings.py
           wsgi.py
        _init_.py
        manage.py
    > venv
    .env
    .gitignore
    Procfile
    README.md
    requirements.txt

Procfile

web: gunicorn project5.project5.wsgi

wsgi.py

import os
 
from django.core.wsgi import get_wsgi_application
 
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'project5.project5.settings')
 
application = get_wsgi_application()

setting.py

import os
from pathlib import Path
from dotenv import load_dotenv

INSTALLED_APPS = [
   'brainSkills',
   'django.contrib.admin',
   'django.contrib.auth',
   'django.contrib.contenttypes',
   'django.contrib.sessions',
   'django.contrib.messages',
   'django.contrib.staticfiles',
]

ROOT_URLCONF = 'project5.urls'

WSGI_APPLICATION = 'project5.wsgi.application'

gunicorn project5.project5.wsgi 或 Heroku local

后出错

Answer 1

尝试更改将其添加到 INSTALLED_APPS 的方式：

INSTALLED_APPS = [
   'django.contrib.admin',
   'django.contrib.auth',
   'django.contrib.contenttypes',
   'django.contrib.sessions',
   'django.contrib.messages',
   'django.contrib.staticfiles',
   'brainSkills.apps.BrainSkillsConfig',
]

有关此内容的更多信息 here。在研究这个问题时，我了解到在 Django 1.7 之前你的方法是正确的如果你也在你的应用程序 __init__.py 中使用了 default_app_config = 'brainSkills.apps.BrainSkillsConfig'。但是 Django 现在推荐我上面显示的方法。
