Couldn't load plugin 'timemanager' due to an error when calling its classFactory() method

[Lukas-J]

Hi,
when trying to activate the TimeManager Plugin in QGIS I get the following error.

Couldn't load plugin 'timemanager' due to an error when calling its classFactory() method 

ModuleNotFoundError: No module named 'future' 
Traceback (most recent call last):

Running pip install future in the terminal solves the problem.

I don't know my ways in QGIS yet, but is it possible to add future as a requirement that gets installed when not already installed when the time manager gets installed?

Thanks!
Lukas
