Failed to load extension problem

chris8574

I get this two errors when I launch Open Sesame:

Failed to load extension file_handler (see debug window for stack trace) 

Failed to load extension pyqode_manager (see debug window for stack trace)

The window stack trace shows:

Traceback:

Thank you

Hi @chris8574 ,

This is probably due to the version of PyQode that you have installed, which is the library that is used for the editor components. OpenSesame requires PyQode ≥ 3, which is a fork of the original (unmaintained) PyQode.

pip:

pip install pyqode3.core pyqode3.python

conda:

conda install pyqode.core pyqode.python -c cogsci

Hope this helps!

Sebastiaan
