ImportError：沒有名爲books.models的模塊

Question

我正在通過虔誠地閱讀this book來學習Django。我在第五章：模型，並且一切正常（在InteractiveConsole中），直到我達到Basic Data Access。

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']

我不知道爲什麼我得到導入錯誤：沒有模塊名爲books.models。
書籍目錄位於當前目錄 mysite（/ home/epqrs/webapps/djcode/mysite/books）。

Answer 1

我不得不把它改成這樣：

from books.models import Publisher, Author, Book 

所以基本上，我不得不採取mysite部分出來。 從'mysite.books'另外，更改安裝的應用程序，只是'books'

我希望它能幫助

Answer 2

我不得不這樣做

from mysite.books.models import Publisher 

，使其工作。
