Answer 1

我测试了一些情况，也是唯一一个在那里我得到了同样的错误是，当我添加的应用程序这在我的项目中不存在于我的INSTALLED_APPS的settings.py文件中。因此，请确保您使用python manage.py startapp polls创建了polls应用程序（您应该有/store/polls文件夹）。

要创建polls应用程序，如果它不存在，您需要先将其从INSTALLED_APPS中删除。如果不先删除它，您将得到与上述相同的错误。

此外，你需要cd到你的项目的根文件夹中运行任何命令（即使不需要它上面的命令）之前，因此，而不是：

python ./store/manage.py runserver 

运行：

cd store/ 
python manage.py runserver
