No module named 'gi' on Arch

[isidoridev]

python installer.py throws an error for a missing module:

File "~/Chicago95/installer.py", line 3, in <module>
import gi
ModuleNotFoundError: No module named 'gi'

Seems the same as #273 , but there is no pip module for "gi" or a package named "python3-gi" when using pacman.
