Mousetrap response item on version 3.2.5
I am trying to install the Mousetrap response item on OpenSesame version 3.2.5.
I had previously installed this on my Open Sesame version 3.1.4 through the instructions on GitHub (https://github.com/PascalKieslich/mousetrap-os) and it worked fine. I am now trying to do this on the updated version following the instructions for 'current development version' from the same link but I get the following error in my debug window:
AttributeErrorTraceback (most recent call last)
----> 1 pip.main(['install', 'https://github.com/PascalKieslich/mousetrap-os/archive/master.zip'])
AttributeError: 'module' object has no attribute 'main'
Does anyone know how the install the mousetrap response in version 3.2.5? Or how do downgrade OpenSesame to a version that supports this type of response? Thank you.
