[RootieWL]

Platform

• { OS version 10.14.5 }
• { psutil version 5.4.7 }

Bug description
{ I tried to import psutil on python but I received an import error, I uninstall psutil and install psutil and I still receive the same error message. }

Traceback (most recent call last):

>>> import psutil

So, as far as I can tell, this import issue happens for Python <3.7. 3.6 seems to be okay. I found this issue has affected my install of the Pants repo.
