Error dukpy when installing OpenSesame with Anaconda

labsupport

When I try to download OpenSesame with Anaconda as described here: Download // OpenSesame documentation, I receive an error involving dukpy when running:

pip install psychopy psychopy-sounddevice

    

        
            
        
    

I don't know if you already noticed and if there is a workaround.

Best,

Hi @labsupport,

I'm not entirely sure how to fix this, but I’ll do my best to help! From the traceback, it looks like the issue occurs because psychopy tries to install dukpy via pip, which requires a C++ build environment.

You could try one of these two options before running pip install psychopy psychopy-sounddevice:

• Option 1: Install the required C++ build tools from Microsoft (or check that they're up to date), then restart your machine and try again.
• Option 2: Install dukpy separately from conda-forge first with conda install conda-forge::dukpy

Let me know if either of these works—or if you find another solution!
