Solved: Installing PsychoPy on Fedora 41

Builder
1

The install process on Linux, I can confirm, is difficult. This is primarily due to difficulties with dependencies of wxwidgets After much trial and error, I am posting a working configuration in case it is helpful to others. Please see the following conda environment.

Installation Steps

conda create -n psychopy python=3.10
conda activate psychopy
pip install attrdict setuptools
pip install --no-binary wxpython wxpython
pip install psychopy

# At this stage if I were to run PsychoPy I would get...
#    ImportError: /lib64/libldap.so.2: undefined symbol: EVP_md2, version OPENSSL_3.0.0
# Using conda-forge libldap instead of the system version corrected this.
conda install openssl openldap
