Please configure the FAIRSPACE_URL environment variable.

I tried to follow the instructions, but

  note: This error originates from a subprocess, and is likely not a problem with pip.
  ERROR: Failed building wheel for numpy

Steps to reproduce:

conda env create -y -n fairspace python=3.7 pip
conda activate fairspace
pip install . 

On MacOS.

I was able to fix this by removing the verion pin from numpy.

Now, I get:

upload_test_data 
2025-06-24 12:55:32,492 [INFO] Reading variable FAIRSPACE_URL from environment.
2025-06-24 12:55:32,492 [ERROR] Please configure the FAIRSPACE_URL environment variable.

echo $FAIRSPACE_URL
http://localhost:8080

Fairspace is running, and the variable is set correctly. But the program still complains.
