django-mongokit 0.2.6 was released in 2013, so it doesn't support Django 1.8.

It looks like your import error has been fixed, but there hasn't been a release since.

You could try installing the master branch. However, you should think carefully about whether you want to base your project on a library that has not had a release since 2013.

# Install master branch
pip install git+git://github.com/peterbe/django-mongokit.git@master

# Or specify commit to install
pip install git+git://github.com/peterbe/django-mongokit.git@b7c10d41675055490a88f7a67f65728465545142

It is showing - requirement already satisfied ----- Requirement already satisfied (use --upgrade to upgrade): pymongo>=2.5 in /var/www/html/admin_python/orahienv/lib/python2.7/site-packages (from mongokit->django-mongokit==0.2.6) – somya singh Jul 19 '17 at 12:31
When it says `requirement already satisfied` for other libraries, that is just for information, it's not an error. If the install command didn't install the master branch, you could try uninstalling it first with `pip uninstall django-mongokit` and then re-installing. – Alasdair Jul 19 '17 at 12:37

In that case you haven't managed to install the master branch, you are still running 0.2.6 which will not work with Django 1.8+ – Alasdair Jul 20 '17 at 07:30
