19483	ImportError is misinterpreted (in contrib.comments)	Valentin Lorentz <progval+django@…>	nobody	"Hi,

I kept having this error when running ""./manage.py runserver"" on a project:


{{{

    raise ImproperlyConfigured(""The COMMENTS_APP setting refers to ""\
django.core.exceptions.ImproperlyConfigured: The COMMENTS_APP setting refers to a non-existing package.
}}}

After loads of debugging, I editted django/contrib/comments/__init__.py: I replaced this:

{{{
    try:
        package = import_module(comments_app)
    exce*pt ImportError:
        raise ImproperlyConfigured(""The COMMENTS_APP setting refers to ""\
                                   ""a non-existing package."")
}}}

by this:

{{{
    package = import_module(comments_app)
}}}


And I got:

{{{
progval@Andromede:~/workspace/lqdn/memopol2-0$ ./manage.py runserver
Error: No module named gunicorn
}}}


I have no idea how to solve this, but you could display the name of the module in the error message, it would help a lot.
