运行服务器在 Django 中找不到模块

Question

我正在尝试开始一个新的 django 项目，我决定按照本教程将我的设置拆分为生产、暂存和开发 https://simpleisbetterthancomplex.com/tips/2017/07/03/django-tip-20-working-with-multiple-settings-modules.html

在运行 python manage.py runserver --settings=mysite.settings.development，我得到这个错误

 File "/home/user/crosspoint/crosspoint-venv/lib/python3.6/site-packages/django/core/management/base.py", line 354, in run_from_argv

During handling of the above exception, another exception occurred:

ModuleNotFoundError: No module named 'crosspoint.settings'

我已尝试检查目录，一切似乎都很好。该项目几乎是空的。请问有什么帮助吗？

这是我开发中的

from .base import *

DEBUG = True

INSTALLED_APPS += [
    'debug_toolbar',
]

MIDDLEWARE += ['debug_toolbar.middleware.DebugToolbarMiddleware', ]

EMAIL_BACKEND = 'django.core.mail.backends.console.EmailBackend'

DEBUG_TOOLBAR_CONFIG = {
    'JQUERY_URL': '',
}

目录是这样的

crosspoint/
 |-- crosspoint/
 |    |-- __init__.py
 |    |-- settings/
 |    |    
 |    |    |-- base.py
 |    |    |-- ci.py
 |    |    |-- development.py
 |    |    |-- production.py
 |    |    +-- staging.py
 |    |-- urls.py
 |    +-- wsgi.py
 +-- manage.py

Answer 1

您的设置文件夹中缺少 __init__.py 文件。没有它，目录就不是 python 模块。

Answer 2

我的目录列表有误。修复目录列表解决了问题。
