我们的问题源于一个Django项目发现了通过Apache/WSGI运行的corsheaders模块。代码在使用Django的本地runserver时运行良好，但在通过Apache（v.2.4.41）访问时抛出500内部服务器错误。如果我们在www.example.com中注解掉应用程序和中间件settings.py，则站点和其他代码运行良好（需要corsheaders的API功能除外）。
我们已经用尽了我们能找到的在线资源，所以提前感谢您的建议，卸载和重新安装django-cors-headers以各种方式使用pip.我们确实使用了其他几个模块，已经通过这个网关安装没有问题.我们可以告诉最好的，问题源于django wsgi没有看到模块.
我在下面包括了相关的日志和设置。我还注意到了corsheader模块的安装位置。

确保你已经安装了corheader。要安装它，你可以尝试pip install django-cors-headers。如果你正在为python包使用virtualenv，那么你必须在apache配置文件中指定virtualenv的位置。

好了，我明白了。我知道这一定是路径挑战，因为模块在那里。如果你看上面，你会pip安装到/home。WSGI是从/user目录工作的。当我强迫Django告诉我其他工作库在哪里时，我看到了这个问题，并强制安装到/user。
指示pip强制重新安装另一个目录的命令是：

sudo pip install --upgrade --force-reinstall --target /usr/lib/python3/dist-packages/ django-cors-headers

Apache/mod_wsgi/Django AJAX ：500内部服务器错误：模块未找到错误：没有名为“corsheaders”的模块
