On Plone 4.3.15, how to install latest Stripe's API

On Plone 4.3.15 (Universal installation), it is not possible to install stripe 2.32.1. See logs :

Getting distribution for 'stripe==2.32.1'.

error: Setup script exited with error in stripe setup command: 'install_requires' must be a string or list of strings containing valid project/version requirement specifiers
An error occurred when trying to install stripe 2.32.1. Look above this message for any errors that were output by easy_install.
While:
  Installing instance.

Error: Couldn't install: stripe 2.32.1

It seems that easy_install / Setuptools is too old ? Do I need to upgrade Setuptool ? If so, how can it be done ?
