如何通过教程解决使用石墨烯django基本设置的ImportError？

Question

我已经开始通过使用Django和GraphQL进行基本设置的graphene_django tutorial。

但是，我无法进展的更多由于导入错误：

ImportError at /graphql 
Could not import 'cookbook.schema.schema' for Graphene setting 'SCHEMA'. ImportError: No module named schema.

你可以看到在最低回购代码here的当前状态。

我认为我的问题与我如何运行服务器有关：python3 manage.py runserver。或者，也许我是如何进口的。但我不知道如何从这里做更多的调试。

一切都完全如教程中所述，没有什么似乎特别不正确的我。如果有问题，我也会用virtualenv来使用Linux。

让我知道你是否需要更多信息我会仔细监控线程。

编辑：Appologies！我用python3和python 2.7运行它，都没有工作。下面是跟踪：

Answer 1

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

对于cookbook.schema要导入的，你就需要将schema.py在内cookbook目录（包含settings.py的一个）。目前，您已将其存储在cookbook目录（包含manage.py的目录）中。要从外部目录导入它，您需要'schema.schema'设置。

有当教程说来'ingredients'添加到INSTALLED_APPS设置（表明它应该是在外cookbook目录）类似的混乱，但代码包括像from cookbook.ingredients.models import ...进口（表明ingredients应该在内部cookbook目录） 。

你可以尝试同时移动schema.py和ingredients目录进入内cookbook目录，并更改INSTALLED_APPS入门到'cookbook.ingredients'，如this repo。
