python - 如何通过教程解决使用 Graphite 烯django基本设置的ImportError？

我已经开始使用Django和GraphQL完成graphene_django tutorial的基本设置。
但是，由于导入错误，我无法继续：

ImportError at /graphql

您可以在最小的repo中看到代码here的当前状态。
我认为我的问题与如何运行服务器有关：python3 manage.py runserver。或者我是怎么进口的。但我不知道如何在这里做更多的调试。
一切都和教程中所说的一模一样，对我来说没有什么特别不正确的地方。如果这很重要的话，我也会在virtualenv中使用Linux。
如果你需要更多的信息，请告诉我，我会仔细监视线程。
编辑：任命！我用python3和python 2.7运行过它，但都没有成功。这是线索：

最佳答案

GRAPHENE = {
    'SCHEMA': 'cookbook.schema.schema'
}

要使cookbook.schema可导入，您需要将schema.py放入内部cookbook目录（包含settings.py的目录）。现在，您可以将它放在外部cookbook目录（包含manage.py的目录）中。要从外部目录导入它，您需要设置中的'schema.schema'。
当教程说要将'ingredients'添加到INSTALLED_APPS设置（建议它应该在外部cookbook目录中）时，也有类似的混淆，但是代码包含了类似from cookbook.ingredients.models import ...的导入（建议ingredients应该在内部cookbook目录中）。
您可以尝试将schema.py和ingredients目录移动到内部cookbook目录，并将INSTALLED_APPS中的条目更改为'cookbook.ingredients'，如this repo中所示。
