maximum recursion depth exceeded in cmp error while executing python manage.py runserver
django, python
Solution
If you haven't already, try installing `python 2.7.5`
I had a similar issue when using django version 1.5.1 and python version 2.7.2. The issue was resolved when I switched to 2.7.5.
To get python 2.7.5 running on your mac, go here and download the Mac Installer for your system. After installing, go to the "Python 2.7" subfolder of the system Applications folder, and double-click on the "Update Shell Profile" to use 2.7.5 from the command line.
After doing that, type `python --version` from the command line to confirm you're using 2.7.5
Hope that helps!
Problem
I'm trying to install Django in my mac. when I run the command python manage.py runserver. I get the error RuntimeError: maximum recursion depth exceeded in cmp. I have pasted my error message below. I even increased the setrecursion limit to 2000 and tried, it didn't work. Any of your help in fixing this is appreciated...
