pkg_resources.DistributionNotFound: The 'django==1.9.1' distribution was not found and is required by kolibri  

Its related to django==1.9.1. Any idea why this is happening???

回答1:

Yeah found an ans , just run the command:

sudo pip install -U djangorestframework

or you can follow the steps:

* first check version of django
* if it is not given as per distrubution package then delete it using following command:
    $ pip uninstall Django
* again install specific version of django:
    $ pip install django==1.9.1  (e.g 1.9.6 or 1.8 or 1.7)
    $ django-admin --version  // 1.9.1
