我测试了一些案例，唯一一个我遇到同样错误的案例是当我将项目中不存在的应用添加到INSTALLED_APPS文件中的settings.py时。因此，请确保您使用polls创建了python manage.py startapp polls个应用（您应该拥有/store/polls文件夹）。

要创建polls应用，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，您将得到与上面相同的错误。

此外，在运行任何命令之前，您需要cd到项目根文件夹（即使上述命令不需要它），所以代替：

python ./store/manage.py runserver

执行命令

cd store/
python manage.py runserver

python ./store/manage.py runserver
