ImportError：沒有名爲diversely.settings.dev的模塊

Question

我剛剛完成了一個django教程，創建設置文件夾並在我的base.py中重新配置我的數據庫後，我的網站沒有加載，一個ImportError。有什麼想法嗎？

這裏的回溯：

Traceback (most recent call last): 
    File "/Users/m.zayas/Desktop/env1/bin/django-admin", line 11, in <module> 
    sys.exit(execute_from_command_line())

文件夾結構： 這裏是我的文件夾結構：

diversely 
    Ldiversely 
    L settings.py 
     L __init__.py 
     L base.py 
     L dev.py 
     L local.py 
     L production.py 

Answer 1

你的文件夾結構應該是這樣的，

- diversely 
    --- __init__.py 
    --- settings 
     ---- __init__.py 
     ---- base.py 
     ---- dev.py 
     ---- production.py 
     ---- local.py 

每個目錄必須包含一個__init__.py文件。如果不是Django提出「找不到模塊」的錯誤。

注意：如果您的文件夾名稱爲「settings.py」，則將其更改爲「設置」。
