Lefse Installation "No ctypes found" error

[UmaJan]

I am attempting to install lefse in a pyhton 3.7 shell (biom-format does not support my system python version 3.6) and am receiving an error upon installing lefse "from _ctypes import Union, Structure, Array
ModuleNotFoundError: No module named '_ctypes'" the libbfi-devel library is present in the global python environment too. I am unsure of why this issue is occuring.
