我是django-oscar的新手，这是我第一次尝试使用它启动网站。尝试加载网页时，我面临以下堆栈跟踪（localhost：8000）。我试图在互联网上搜索很多，但我找不到任何解决方案。

此外，如果您可以为django建议更好或更不容易出错的电子商务框架，那就太棒了！

Answer 1

我遇到了这个问题，因为我在settings.py中使用了MIDDLEWARE而不是MIDDLEWARE_CLASSES。我一改变了，一切都运转了。

Answer 2

oscar.apps.basket.middleware.BasketMiddleware设置中缺少middleware。

Django oscar <wsgirequest get =“”>中的密钥[basket]查找失败
