When I tried to fire up Django server using manage.py, I kept getting this
error,which is cause by from django.test.utils import compare_xml. It turns
out that I'm using the wrong Django version (1.4), and I should
upgrade to 1.5.
The easiest way to upgrade is using easy_install
# install easy_install if you haven't done so
sudo apt-get install python-setuptools
# now upgrade
sudo easy_install --upgrade django
And the python file that actually contains the compare_xml method is located
in (in my case):
/use/local/lib/python2.7/dist-packages/Django-1.5.2-py2.7.egg/django/test/utils.py
But in the process of figuring out this issue, I learned several things.
-
When importing django modules, e.g., you have to define the
DJANGO_SETTINGS_MODULESenvironment variable. Just set it to your project'ssettings.pywill be OK. -
To find out what methods are provided in a module and various other information, say
django.test.utils, you can use this command in shell:
$ DJANGO_SETTINGS_MODULES=settings python -c "import django.test.utils;help(django.test.utils);"
