Django-configurations 在使用 UWSGI 时找不到我的配置

Question

我正试图将Django==2.1项目从一个AWS实例迁移到另一个实例。我没有创建这个项目，所以我不确定他们在部署时遵循的所有步骤。我看到uWSGI==2.0.19.1在requirements.txt文件中，所以我试图使用它在8000端口运行项目。

该项目还使用库django-configurations==2.1来管理多个配置。它们位于一个名为config的文件夹中。

project/
  config/
    __init__.py
    common.py
    development.py
    local.py
    production.py
    staging.py
  manage.py
  wsgi.py
  ...

config文件夹中的__init__.py文件包含以下内容：

from __future__ import absolute_import
from .local import Local
from .staging import Staging
from .production import Production
from .development import Development

我正在尝试运行以下命令：
uwsgi --http :8000 --module wsgi:application --chdir=/path/to/project
我收到了此错误：

Traceback (most recent call last):
  File "./wsgi.py", line 16, in <module>
    from configurations.wsgi import get_wsgi_application
  File "/path/to/project/.env/lib/python3.6/site-packages/configurations/wsgi.py", line 14, in <module>
    application = get_wsgi_application()
  File "/path/to/project/.env/lib/python3.6/site-packages/django/core/wsgi.py", line 12, in get_wsgi_application

    cls = getattr(mod, self.name)

*** no app loaded. going in full dynamic mode ***
*** uWSGI is running in multiple interpreter mode ***

因此，这似乎是django配置的一个问题，但如果我只是用DJANGO_CONFIGURATION=Production manage.py runserver 0.0.0.0:8000运行服务器，它就可以正常工作。

如果我试图运行在django shell中抛出错误的同一行代码，它会起作用：

Python 3.6.9 (default, Jul 17 2020, 12:50:27) 
[GCC 8.4.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
(InteractiveConsole)
>>> import config
>>> getattr(config, 'Production')
<Configuration 'config.production.Production'>

wsgi.py文件包含以下内容：

import os
if os.getenv('local_settings'):
    os.environ.setdefault("DJANGO_SETTINGS_MODULE", "local.settings")
    from django.core.wsgi import get_wsgi_application
else:
    os.environ.setdefault("DJANGO_SETTINGS_MODULE", "config")
    os.environ.setdefault("DJANGO_CONFIGURATION", "Production")
    from configurations.wsgi import get_wsgi_application
from whitenoise.django import DjangoWhiteNoise
application = get_wsgi_application()
application = DjangoWhiteNoise(application)

我很感激能得到的任何帮助。

您的uwsgi配置有点混淆

[uwsgi]
basedir = %d
chdir = %(basedir)
master=True
vacuum=True
max-requests=5000
pythonpath = %(basedir)src/
wsgi-file  = %(basedir)src/bear/wsgi.py
env = DJANGO_SETTINGS_MODULE=bear.settings.production
; -- Static serve
mimefile   = %(basedir)uwsgi.mime
static-gzip-all = true
static-check = %(basedir)public
static-safe = %(basedir)public

创建一个uwsgi.ini文件，在其中定义：

• pythonpath=定义项目的主目录
• wsgi file=找到django-uwsgi.py文件
• env=uwsgi将在生产模式下运行。定义环境
• static-check=找到静态文件管理器，或者您可以使用nginx为其提供服务。您可以选择collectstatic
• mimefile=mimefile.mime

uwsgi --ini uwsgi.ini --http :8000
