Issue running saved experiment Ubuntu 18.04

OS (e.g. Win10): Ubuntu 18.04 LTS
PsychoPy version (e.g. 1.84.x): v 3.1.0
Standard Standalone? (y/n) If not then what?: no, Psypy3 environment in Anaconda

Hello! I have been struggling to install PsychoPy on my system for a while, and I finally got the builder to open via the Psypy3 environment in Anaconda. However, when I try to run an experiment, I get the following error message:

######## Running: /home/prohrer/Desktop/PsychoPy/digit_span/DS_Adapt.py ########
1.3813 WARNING Import Error: No module named ‘psychtoolbox’. Using event module for keyboard component.
Traceback (most recent call last):
File “/home/prohrer/Desktop/PsychoPy/digit_span/DS_Adapt.py”, line 34, in
dlg = gui.DlgFromDict(dictionary=expInfo, sortKeys=True, title=expName)
TypeError: init() got an unexpected keyword argument ‘sortKeys’

I’m fairly new to both programming and linux in general, so any (detailed) help to get PsychoPy up and running on my computer would be greatly appreciated!!
