我知道这是一个老线程,但我刚刚碰到同样的问题,我不认为这是由于缺少包裹造成的.由于Django核心发行版已包含正确的wsgi处理程序.

这里的问题是,当执行wsgi.py时,它缺少来自virtualenv的site-packages包.(如果你已经激活了你的virtualenv,并完成了pip install django,那么一切都很好.你有必要的django包).

就我而言,我修复了在Path/to/Project/Project/wsgi.py文件中修改sys.path的问题.

您必须将项目目录和virtualenv站点包附加到sys.path列表.这是我的项目中包含的wsgi.py文件(谈论用django-admin.py start-project创建的wsgi.py)...我必须修改才能使它与Apache一起工作

# =====================
# wsgi.py file begin 

import os, sys
# add the hellodjango project path into the sys.path
sys.path.append('<PATH_TO_MY_DJANGO_PROJECT>/hellodjango')

# add the virtualenv site-packages path to the sys.path
sys.path.append('<PATH_TO_VIRTUALENV>/Lib/site-packages')

# poiting to the project settings
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "hellodjango.settings")

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

# wsgi.py file end
# ===================

确保:

1. 你将mod_wsgi添加到Apache模块dir mod_wsgi必须为你拥有的操作系​​统,Apache和Python版本编译

2. 将load module命令添加到httpd.conf中以加载mod_wsgi模块LoadModule wsgi_module modules/mod_wsgi.so

3. 在httpd.conf中配置Django细节或者在httpd.conf中包含任何conf

基于文档如何使用Django与Apache和mod_wsgi

WSGIScriptAlias / <PATH_TO_PROJECT>/hellodjango/hellodjango/wsgi.py
WSGIPythonPath <PATH_TO_PROJECT>:<PATH_TO_VIRTUALENV>/Lib/site-packages

<Directory <PATH_TO_PROJECT>/hellodjango/hellodjango> 
  <Files wsgi.py>
    Order deny,allow
    Require all granted
  </Files>
</Directory>

希望这可以帮助.它对我有用.

Answer 2

我遇到过同样的问题。我的 libapache2-mod-wsgi 是 python 2.x 而不是 python 3.x

在这里找到了解决方案：https : //stackoverflow.com/a/28118284/2489042

归功于@nima

$ sudo apt-get remove libapache2-mod-python libapache2-mod-wsgi
$ sudo apt-get install libapache2-mod-wsgi-py3

复制/粘贴这些命令之前来自@alxs 的警告：如果服务器上运行的 python 2 项目使用 wsgi 和 apache，上述命令将有效地关闭它们。

Answer 3

将其添加到Apache配置文件:

WSGIPythonHome /home/ec2-user/.virtualenvs/mysite-main
