当我在mod_wsgi下部署Django 3.0.5时，我得到一个错误：AttributeError: 'HttpResponse' object has no attribute '_resource_closers'。我正在运行：

• Python：3.6.8
• Django：3.0.5
• Apache：2.4.6
• mod_wsgi：4.6.2

下面是导致错误的视图的基本信息;没有什么特别的（我已经简化了meetings_struct的代码）：

class MeetingsAPIView(MeetingsBaseView):
    def get(self, request, *args, **kwargs):
        meetings = self.get_meetings()
        meetings_struct = []
        for meeting in meetings:
            meetings_struct.append({
                "id": meeting.id,
                "name": meeting.title,
                "slug": meeting.slug,
            })
        return HttpResponse(meetings_struct, content_type="application/json")

如果我激活venv并在端口80的服务器上手动使用runserver，相同的视图不会给予错误。当相同的代码和venv在Apache下运行时，以下是Apache日志中的错误：

我已经回滚到以前的版本，运行Django 2.2;堆栈的其余部分相同。这一点让我感到困惑，因为使用Apache配置使用的相同venv的相同部署代码在runserver下工作正常，但在mod_wsgi上出错。
我尝试过停止并启动Apache，再次运行发布过程以获得新的venv和代码库，甚至重新启动服务器。同样的错误也会发生，但仅在Apache / mod_wsgi下。
有什么办法吗？我很困惑！
