内容：有没有人和我一样 复制上面的代码到 blog/admin.py 页面下注册，会出现报错 打不开网站，找不到什么原因，我的python是 3.8 Django是最新版的 pycharm也是最新版的2020.2
报错如下：
class ArticleAdmin(admin.ModelAdmin):

后面我发现是 @admin.register 这个改为 @admin.site.register 后 就报错如下
return _bootstrap._gcd_import(name[level:], package, level)
File "<frozen importlib._bootstrap>", line 1014, in _gcd_import

有谁解决了吗？ 请教下
