下面是我尝试在Debian 11服务器上部署Django==3.2.12，wagtail==2.16.1，python 3.8.2，mod_wsgi 4.9时的错误。我在末尾有一个完整的堆栈跟踪。
class SimpleLazyObject(LazyObject):
TypeError: Error when calling the metaclass bases
'property' object is not callable
当我在我的本地开发机器(Mac(上运行这个程序时，它运行得很好。我发现有人也有同样的问题，但不清楚是如何解决的。
我一直在使用的资源是1，2，3，4。我尝试过使用pip和从源代码安装mod_wsgi。为Apache2配置使用了各种指南。从python 3.8升级到3.9，并降级到3.7。
Create interpreter '0.0.0.0|'.

我遇到了同样的问题，所以我做了以下步骤：
使用以下命令删除apache2库-sudo apt-get删除python pip apache2 libapache2 mod wsgi
然后使用以下命令安装正确的库-sudo apt-get安装python3 pip apache2 libapache2-mod-wsgi-py3
这解决了我的错误。
