如何通過教程解決使用石墨烯django基本設置的ImportError？

Question

我已經開始通過使用Django和GraphQL進行基本設置的graphene_django tutorial。

但是，我無法進展的更多由於導入錯誤：

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

你可以看到在最低迴購代碼here的當前狀態。

我認爲我的問題與我如何運行服務器有關：python3 manage.py runserver。或者，也許我是如何進口的。但我不知道如何從這裏做更多的調試。

一切都完全如教程中所述，沒有什麼似乎特別不正確的我。如果有問題，我也會用virtualenv來使用Linux。

讓我知道你是否需要更多信息我會仔細監控線程。

編輯：Appologies！我用python3和python 2.7運行它，都沒有工作。下面是跟蹤：

Answer 1

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

對於cookbook.schema要導入的，你就需要將schema.py在內cookbook目錄（包含settings.py的一個）。目前，您已將其存儲在cookbook目錄（包含manage.py的目錄）中。要從外部目錄導入它，您需要'schema.schema'設置。

有當教程說來'ingredients'添加到INSTALLED_APPS設置（表明它應該是在外cookbook目錄）類似的混亂，但代碼包括像from cookbook.ingredients.models import ...進口（表明ingredients應該在內部cookbook目錄） 。

你可以嘗試同時移動schema.py和ingredients目錄進入內cookbook目錄，並更改INSTALLED_APPS入門到'cookbook.ingredients'，如this repo。
