Good afternoon,
I’m currently using Django 1.5.1 and Python 3.3
I have what seems to be an odd error that up until now I’ve been ignoring
as it hasn’t appeared to harm any functionality of my deployed application.
However - a couple of days ago I wanted to look into adding
compression/minification of my javascript and css files and looked into
adding django-pipeline using cssmin and jsmin compression which as I
understand hooks into staticfiles management when collectstatic is run.
Currently when I run collectstatic when deploying to my test server I get a
‘TypeError: issubclass() arg 1 must be a class’ error. Yet, when I run my
application the staticfiles have been collected and put into the correct
folder (hence why I have been ignoring the error).
Well… pipeline doesn’t appear to be compressing any files and I’m wondering
what I’ve done. Have I not implemented pipeline properly? Is collectstatic
working properly or is it shutting down after the error and subsequently
failing to run pipeline?
Any help would be appreciated - Googling this problem hasn't really helped.
Thanks for your time.
Nesh
