2009 Mac Pro/OSX El Capitan, 2015 Macbook Pro/OSX Catalina, 2010 MacPro/OSX El Capitan
Anaconda installed Psychopy (python v 3.6.6)
I don’t have this error on my 2017 Macbook Pro/OSX Mojave, either using standalone or anaconda psychopy
I’m trying to run a code called “RTBox_light_demo.py” that can be downloaded from this site. It is used to communicate with a response box that is connected with USB.
It gives me the following error:
Traceback (most recent call last): File "/Users/user/Downloads/RTBox_python_000/RTBox_light_demo.py", line 15, in <module> import RTBox File "/Users/user/Downloads/RTBox_python_000/RTBox.py", line 14, in <module> from pynput import keyboard File "/Users/user/anaconda3/envs/psypy3/lib/python3.6/site-packages/pynput/__init__.py", line 40, in <module> from . import keyboard File "/Users/user/anaconda3/envs/psypy3/lib/python3.6/site-packages/pynput/keyboard/__init__.py", line 40, in <module> from ._darwin import KeyCode, Key, Controller, Listener File "/Users/user/anaconda3/envs/psypy3/lib/python3.6/site-packages/pynput/keyboard/_darwin.py", line 144, in <module> class Listener(ListenerMixin, _base.Listener): File "/Users/user/anaconda3/envs/psypy3/lib/python3.6/site-packages/pynput/keyboard/_darwin.py", line 148, in Listener Quartz.CGEventMaskBit(Quartz.kCGEventKeyUp) | File "/Users/user/anaconda3/envs/psypy3/lib/python3.6/site-packages/objc/_lazyimport.py", line 181, in __getattr__ raise AttributeError(name) AttributeError: CGEventMaskBit
The error seems to originate from “RT_light_demo.py” first stating:
from psychopy import visual, event, core
And then states:
In which the line
from pynput import keyboard consequently prompts the error.
If I remove
visual from the first line,
from pynput import keyboard does not give an error, but I obviously get other errors further down the script. If I import
visual after I import
RTBox , The script gets stuck at presenting the subject instruction screen (the first screen presented).
Any ideas how to solve this?
