Question

我正在通过阅读来学习 Django this book虔诚地。我在第 5 章:模型，并且一切正常(在 InteractiveConsole 中)，直到我到达 Basic Data Access .

epqrs@epqrs:~/webapps/djcode/mysite$ pwd
/home/epqrs/webapps/djcode/mysite
epqrs@epqrs:~/webapps/djcode/mysite$ python ../manage.py shell

(InteractiveConsole)
>>> from books.models import Publisher
Traceback (most recent call last):

ImportError: No module named books.models
>>> import sys
>>> sys.path

我不明白为什么会出现 ImportError: No module named books.models。
books 目录位于当前目录 mysite (/home/epqrs/webapps/djcode/mysite/books) 下。

Answer 1

我不得不将其更改为:

from books.models import Publisher, Author, Book

所以基本上，我必须删除 mysite 部分。此外，将已安装的应用程序从 'mysite.books' 更改为仅 'books'

希望对你有帮助
