'requests' module dependency issue

[Barukimang]

Updated from python2 to python2, including all dependencies. Now python-mpesa module gives dependency errors:

ERROR: social-auth-core 3.2.0 has requirement requests>=2.9.1, but you'll have requests 2.8.1 which is incompatible.
ERROR: googlemaps 4.0.0 has requirement requests<3.0,>=2.20.0, but you'll have requests 2.8.1 which is incompatible.
ERROR: django-oauth-toolkit 1.2.0 has requirement requests>=2.13.0, but you'll have requests 2.8.1 which is incompatible.
ERROR: africastalking 1.1.9 has requirement requests>=v2.18.4, but you'll have requests 2.8.1 which is incompatible.

Could this be updated? I have 'requests==2.20.0' installed
