Django and Pytz what is going wrong? - django

Question

I'm currently trying to make Django1.6b2 with Python3.3 work on my server.
I got so many problems for now that I just can't list them (Flup, Threading, FastCGI) and finally I'm almost there. Here is my django.fcgi :
#!/home/benjamin/Python/3.3/bin/python3
import os, sys
import django
print("Django Version : {}".format(django.VERSION))
print("Python Version : {}".format(sys.version[:3]))
_PROJECT_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
sys.path.insert(0, _PROJECT_DIR)
sys.path.insert(0, os.path.dirname(_PROJECT_DIR))
_PROJECT_NAME = _PROJECT_DIR.split('/')[-1]
os.environ['DJANGO_SETTINGS_MODULE'] = "%s.settings" % _PROJECT_NAME
from django.core.servers.fastcgi import runfastcgi
runfastcgi(method="threaded", daemonize="false")
And here is my traceback :
Traceback (most recent call last):
File "website/public/django.fcgi", line 17, in <module>

return StringIO(*args,**kw)
TypeError: initial_value must be str or None, not bytes
How can I solve that ? It seems that Django tries to import a module that I can't find with pip-3.3 (pytz-2013b-py2.6.egg) it's 2.6 and why does pip install that ? xD
Could someone help me ? =)

Answer 1

It looks like a bug in distribute package for python3 at the following location -
pkg_resources.py -> get_resource_string
this method returns bytes and StringIO is expecting for string.
I tried to decode it by using decode("ISO-8859-1") method then I got error in pytz package.
However I got the workaround for this -
Change "./pytz-2013.7-py3.3.egg" to "./pytz" in
"site-packages/easy-install.pth" file.
Make sure you have unzipped pytz directory in your site-packages
directory.
