TypeError:
login() got an unexpected keyword argument ‘extra_context’
Error location File"/Users/user/Desktop/DjangoStudy/extra_app/xadmin/views/website.py", line 65, in get return login(request, **defaults)
登入登出界面都会出现这个Error，上方法：
因为之前有用过pip下载版本的xadmin2 当时没有出现这个Error，然后就去那个版本的包里看了一下xadmin/views/website.py文件 发现确实有很多不一样，而且不会报错，厉害的同学可以仔细看看，新手可以简单粗暴直接将Website.py文件替换掉
不会报错的webiste.py文件如下
