Question

After installing Django, I followed the tutorial Playing with the API. When I run the following command.

python manage.py shell

I got this error message.

  File "/Library/Python/2.6/site-packages/django/core/management/commands/shell.py", 
  line 29, in handle_noargs
    shell = IPython.Shell.IPShell(argv=[])
  AttributeError: 'module' object has no attribute 'Shell'

I checked that I have Shell.py module, and IPShell class inside it.

/Library/Python/2.6/site-packages/IPython/Shell.py

class IPShell:
    """Create an IPython instance."""

What’s wrong with this? My IPython/Python/OS is as follows.

• Mac OS X 10.6.5
• Python 2.6.1
• IPython version 0.10.1

ADDED

>>> import IPython
>>> IPython.Shell
Traceback (most recent call last):
  File "", line 1, in 
AttributeError: 'module' object has no attribute 'Shell'
>>> print IPython.__file__
/Library/Python/2.6/site-packages/IPython/__init__.py

SOLVED

With ma3 and Ignacio’s help, I could solve this issue.

1. Remove site-package/IPython and site-package/ipython*.egg
2. sudo easy_install ipython to fresh install the IPython

3. Apply the patch to the django’s shell.py as Ignacio linked.

       try:
           shell = IPython.InteractiveShell()
       except AttributeError:
           # IPython < 0.11
           # Explicitly pass an empty list as arguments, because otherwise IPython
           # would use sys.argv from this script.
           shell = IPython.Shell.IPShell(argv=[])
       shell.mainloop()
   

Answer 1

A change was made to IPython back in August 19, 2009 that removed this name, and Django hasn’t caught up yet. So, Django bug.

EDIT:

And here it is.
