importorror:没有名为books.models的模块

Question

我是通过虔诚地阅读来学习Django的。我在第5章：模型中，在到达Basic Data Access之前，一切都很好（在InteractiveConsole中）

epqrs@epqrs:~/webapps/djcode/mysite$ pwd
/home/epqrs/webapps/djcode/mysite
epqrs@epqrs:~/webapps/djcode/mysite$ python ../manage.py shell
Python 2.7.3 (default, Sep 26 2012, 21:51:14) 
[GCC 4.7.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
(InteractiveConsole)
>>> from books.models import Publisher
Traceback (most recent call last):
  File "<console>", line 1, in <module>
ImportError: No module named books.models
>>> import sys
>>> sys.path
['/home/epqrs/webapps/djcode', '/usr/lib/python2.7', '/usr/lib/python2.7/plat-linux2', '/usr/lib/python2.7/lib-tk', '/usr/lib/python2.7/lib-old', '/usr/lib/python2.7/lib-dynload', '/usr/local/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages/PIL', '/usr/lib/python2.7/dist-packages/gst-0.10', '/usr/lib/python2.7/dist-packages/gtk-2.0', '/usr/lib/python2.7/dist-packages/ubuntu-sso-client', '/usr/lib/python2.7/dist-packages/ubuntuone-client', '/usr/lib/python2.7/dist-packages/ubuntuone-control-panel', '/usr/lib/python2.7/dist-packages/ubuntuone-couch', '/usr/lib/python2.7/dist-packages/ubuntuone-storage-protocol']

我不明白为什么我得到importorror：没有名为books.models的模块
books目录位于当前目录下mysite（/home/epqrs/webapps/djcode/mysite/books）。

Answer 1

我不得不改成这样：

from books.models import Publisher, Author, Book

所以基本上，我必须去掉mysite部分。 另外，将已安装的应用程序从'mysite.books'更改为'books'

我希望能帮上忙

Answer 2

我不得不这么做

from mysite.books.models import Publisher

让它工作。
