HTTP 500 错误 - 目标 WSGI 脚本无法作为 Python 模块加载

Question

我在使用 bitnami django 时遇到了上述错误。 根据文档完成所有设置： https://docs.bitnami.com/virtual-machine/components/django/#production python版本：Python 3.6.4 :: Anaconda, Inc. django 版本：2.0.2-3

wsgi.py:

import os,sys
sys.path.append('/Applications/djangostack-2.0.2-3/apps/django/django_projects/MyProject')
os.environ.setdefault("PYTHON_EGG_CACHE", "/Applications/djangostack-2.0.2-3/apps/django/django_projects/MyProject/egg_cache")
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "MyProject.settings")

from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()

httpd-app.conf：

<IfDefine !IS_DJANGOSTACK_LOADED> 
Define IS_DJANGOSTACK_LOADED
WSGIDaemonProcess wsgi-djangostack   processes=2 threads=15    display-name=%{GROUP}

    </IfVersion>

    WSGIProcessGroup wsgi-djangostack

</Directory>

Alias /MyProject/static "/Applications/djangostack-2.0.2-3/apps/django/lib/python3.6/site-packages/Django-2.0.2-py3.6.egg/django/contrib/admin/static"
WSGIScriptAlias /MyProject '/Applications/djangostack-2.0.2-3/apps/django/django_projects/MyProject/MyProject/wsgi.py'

httpd-prefix.conf：

# Include file
Include "/Applications/djangostack-2.0.2-3/apps/django/django_projects/MyProject/conf/httpd-app.conf"

对应的 url 添加到 /Applications/djangostack-2.0.2-3/apache2/conf/bitnami/bitnami-apps-prefix.conf 文件

但是当我尝试通过浏览器访问应用程序时，日志中出现错误：

我已经安装了 widget_tweaks 使用：

pip3 install django-widget-tweaks 

但是当我停止 Apache 并使用命令运行应用程序时

python3 manage.py runserver localhost:8080 

该应用运行良好。

我在 /Applications/djangostack-2.0.2-3/apps/django/django_projects/MyProject/MyProject 下的 urls.py 看起来像：

from django.contrib import admin
from django.urls import path, include,re_path

urlpatterns = [
    path('', include('APP.urls')),
    re_path(r'^admin/', admin.site.urls, name='admin'),
]

所以我假设 Apache 配置中存在错误。任何帮助或建议将不胜感激！

Answer 1

感谢 Jota 提供解决方案之一。

解决方案 1： 对于 Mac OS，当我执行 /Applications/djangostack-2.0.2-3/use_djangostack 时，我进入 Bitnami 控制台。 我只需要安装所有必要的模块，并且自定义项目使用 apache 成功运行。

解决方案 2： 如果您不想使用 bitnami 控制台，

1) 使用 pip 安装 mod_wsgi，最好安装到 Python 虚拟环境中。确保 pip 适用于您要使用的 Python 版本。

pip install mod_wsgi 

2) 通过运行显示要添加到 Apache 配置文件以加载此 mod_wsgi 的配置：

mod_wsgi-express module-config

3) 获取上述命令的输出以显示配置并添加到 Apache 配置。 (httpd.conf 文件)

4) 使用 ctlscript.sh 文件重新启动 apache。在我的情况下，命令看起来像：

/Applications/djangostack-2.0.2-3/ctlscript.sh restart apache

5) 重启后，我的自定义项目运行成功。

问候，
