Deployment error. Error running WSGI application. ModuleNotFoundError: No module named 'api.urls'

问题

To fix the "ModuleNotFoundError: No module named 'api.urls'" error, you need to ensure that your project structure and configurations are correctly set up. Here's a checklist of things to verify:

  1. Directory Structure:

    • Confirm that your project structure is consistent with Django conventions.
    • Check that the "api" app is located inside your main project directory, which seems to be "/home/danialsk/unitree/unitree" based on your WSGI file.

  2. Python Path:

    • Ensure that you've added the correct path to your project directory in your WSGI file. It appears to be correctly set in your provided code:

      path = '/home/danialsk/unitree/unitree'

  3. Django Settings:

    • Verify that you've set the correct value for the "DJANGO_SETTINGS_MODULE" environment variable in your WSGI file. It should point to your Django project's settings module, as you've done:

      os.environ['DJANGO_SETTINGS_MODULE'] = 'unitree.settings'

  4. Installed Apps:

    • Double-check that you have included the "api" app in your Django project's "INSTALLED_APPS" list in the "settings.py" file:

      INSTALLED_APPS = [
    ...
    'api',
    ...
]

  5. URLs Configuration:

    • Ensure that the "api.urls" module is correctly referenced in your "features/urls.py" file:

      path('api/', include('api.urls')),

  6. Virtual Environment:

    • Make sure you are using the correct virtual environment where you installed your project dependencies.

  7. Restart Server:

    • After making these changes, restart your web server to apply the configuration changes.

If you've verified all these points and are still encountering the error, please provide more details about your project's directory structure and any other relevant configuration files for further assistance.

How to fix that?

得分: 0

你需要将 path 设置为根目录（manage.py 所在的位置），所以请将你 wsgi 文件中的 path 从以下内容：

path = '/home/danialsk/unitree/unitree'

修改为：

path = '/home/danialsk/unitree'

另外，你的 unitree.urls 中存在重复的 urlpattern，请将其更新为如下内容：

from django.contrib import admin
from django.urls import path, include
from django.conf import settings
from django.conf.urls.static import static

urlpatterns = [
    path('admin/', admin.site.urls),
    path('', include('features.urls')),
]

urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
urlpatterns += static(settings.STATIC_URL, document_root=settings.STATIC_URL)
英文:

You've to set path to root directory (where manage.py lies)
so change your path in wsgi file from this

path = '/home/danialsk/unitree/unitree'

to this

path = '/home/danialsk/unitree'

and you've duplicate urlpattern in your unitree.urls
update it like this

from django.contrib import admin
from django.urls import path, include
from django.conf import settings
from django.conf.urls.static import static

urlpatterns = [
    path('admin/', admin.site.urls),
    path('', include('features.urls')),
]


urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
urlpatterns += static(settings.STATIC_URL, document_root=settings.STATIC_URL)
