我试图让我的 cookiecutter-django 应用程序在 Apache 下运行，并通过 pip 安装 mod_wsgi。

python3 manager.py runserver作品。

但是在 Apache 中运行它后，我收到一条错误消息，提示找不到模块配置。所以我pip install config。（它没有安装在我的开发系统上。）

这将一个 config.py 文件放在我的 /usr/local/pulseenv/lib/python3.5/site-packages 中。

该文件有我修复的各种语法错误。据我所知，这些错误是由于 python 2.7 和 3.5 之间的变化造成的。

但现在我得到了这个错误，我被困在哪里去：

ImportError: No module named 'config.settings'; 'config' is not a package

我在 error.log 中没有看到任何关于如何进一步跟踪错误的线索。那么这个模块是什么？为什么我需要它？以及如何找出我的问题是？

这是我的虚拟主机文件（/etc/apache2/sites-available/000-default.conf）：

我确实有一个配置目录：

ubuntu@ip-172-31-84-213:~$ cd /var/www/pulsemanager/config/
ubuntu@ip-172-31-84-213:/var/www/pulsemanager/config$ ls
__init__.py  __pycache__  settings  urls.py  wsgi.py
ubuntu@ip-172-31-84-213:/var/www/pulsemanager/config$ cd settings
ubuntu@ip-172-31-84-213:/var/www/pulsemanager/config/settings$ ls
base.py  __init__.py  local.py  production.py  __pycache__  test.py
ubuntu@ip-172-31-84-213:/var/www/pulsemanager/config/settings$

这是我的 wsgi.py。似乎 DJANGO_SETTINGS_MODULE 应该默认为 config.settings.production (/var/pulsemanager/config/settings/production.py)：

"""
WSGI config for pulsemanager project.


"""
import os
import sys

from django.core.wsgi import get_wsgi_application

# This allows easy placement of apps within the interior
# pulsemanager directory.
app_path = os.path.dirname(os.path.abspath(__file__)).replace('/config', '')
sys.path.append(os.path.join(app_path, 'pulsemanager'))

if os.environ.get('DJANGO_SETTINGS_MODULE') == 'config.settings.production':
    from raven.contrib.django.raven_compat.middleware.wsgi import Sentry

# We defer to a DJANGO_SETTINGS_MODULE already in the environment. This breaks
# if running multiple sites in the same mod_wsgi process. To fix this, use
# mod_wsgi daemon mode with each site in its own daemon process, or use
# os.environ["DJANGO_SETTINGS_MODULE"] = "config.settings.production"
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "config.settings.production")

# This application object is used by any WSGI server configured to use this
# file. This includes Django's development server, if the WSGI_APPLICATION
# setting points here.
application = get_wsgi_application()
if os.environ.get('DJANGO_SETTINGS_MODULE') == 'config.settings.production':
    application = Sentry(application)
# Apply WSGI middleware here.
# from helloworld.wsgi import HelloWorldApplication
# application = HelloWorldApplication(application)

我删除了配置包。我很确定那是一条红鲱鱼。我看到几个对“配置”的引用，例如 os.environ.setdefault("DJANGO_SETTINGS_MODULE", "config.settings.production")在app_path = os.path.dirname(os.path.abspath(__file__)).replace('/config', '') wsgi.py 中。这些事情之一是我的问题所在吗？

我添加export DJANGO_SETTINGS_MODULE=config.settings.production到config/__init__.py甚至尝试放在os.environ["DJANGO_SETTINGS_MODULE"] = "config.settings.production"wsgi.py 的顶部附近。

我将 WSGIDaemonProcess 更新为：

WSGIDaemonProcess pulsemanager python-home=/usr/local/pulseenv/  python-path=/var/www/pulsemanager/pulsemanager:/usr/local/pulseenv/lib/python3.5/site-packages

但我仍然得到：

ImportError: No module named 'config'

您DJANGO_SETTINGS_MODULE需要指定项目根文件夹中存在的包或模块。

[pulsemanager]/
├── [config]/
│   ├── __init__.py
│   ├── settings.py
│   ├── urls.py
│   └── wsgi.py
└── manage.py

虚拟环境

使用 mod_wsgi 守护进程模式

WSGIDaemonProcess pulsemanager python-home=/path/to/venv/
WSGIProcessGroup pulsemanager

对于在单个 mod_wsgi 进程中运行的多个站点，所有站点都将使用碰巧首先运行的站点的设置。这可以通过更改来解决：

os.environ["DJANGO_SETTINGS_MODULE"] = "{{ project_name }}.settings.{{env}}"

更新了 wsgi.py

import os
import sys

from django.core.wsgi import get_wsgi_application

sys.path.insert(0, os.path.dirname(os.path.abspath(__file__)))
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "pulsemanager.settings.production")

if os.environ.get("DJANGO_SETTINGS_MODULE") == "pulsemanager.settings.production":
    from raven.contrib.django.raven_compat.middleware.wsgi import Sentry
    application = Sentry(get_wsgi_application())
else:
    get_wsgi_application()

从没有初始化文件的本地文件夹导入时，我遇到了同样的问题，因为这会使它成为循环导入。

尝试echo $PYTHONPATH，将此变量重置为空白对我有用。

Run django from linux terminal, not vs code terminal

  • I had this crazy experience only when using vs code terminal
  • activate your virtual env and run from the default linux terminal
  • (app_venv)machinery@001:~/Desktop/yourprj$ ./manage.py runserver

我曾经遇到过与上述类似的问题：

$ py -3 bloody.py
Traceback (most recent call last):
  File "bloody.py", line 1, in <module>
    import requests
ModuleNotFoundError: No module named 'requests'

即使我遵循了 Cisco Devnet 网站上的说明，也会发生这种情况，该网站建议：

pip install requests

我最终运行的是：

py -2 -m pip install requests

py -3 -m pip install requests

这requests为 Python 3 和 Python 2 安装。
