I have virtualenv with old django 1.3. I must use this version but when I install:
pip install django-debug-toolbar
django-debug-toolbar package is closely tied to specific versions of Django; the latest package requires Django 1.4.2 or newer and that is stated in the requirements:
install_requires=[ 'django>=1.4.2,<1.7', 'sqlparse', ],
and on the PyPI page:
The current version of the Debug Toolbar is 0.11.0. It works on Django 1.4, 1.5 and 1.6.
You need to install an older version of the package; 0.10.0 upgraded the minimum version requirement from Django 1.3 to 1.4, so 0.9.4 is the most recent version that still works with your older Django setup:
pip install django-debug-toolbar==0.9.4
