django-debug-toolbar and django-admin-bootstrapped have conflict with Django 1.7

[imansh77]

django-debug-toolbar 1.10.1 has requirement Django>=1.11, but you'll have django 1.8 which is incompatible.
when I try to install Django 1.11 then the problem is :
django-admin-bootstrapped 2.5.7 has requirement Django<1.9,>=1.8, but you'll have django 1.11 which is incompatible.
