Using linux for poke env yields ConstantTeambuilder object has no attribute '_mons'

[AlanOsys]

As the title says I get this error only on linux. I use the same code on Windows and it works fine, but I wish to use it on linux.

The issue seems to stem from poke_env/teambuilder/constant_teambuilder.py specifically in return self._mons

It works if i dont use a custom team builder, but its something i would really want to use

I wonder if this has to do with carriage return (\r\n) v. line feed (\n). Most editors give you the option to choose. If yours does, can you try changing it and see if it fixes this issue?
