Problem using PYTHONPATH in pants run goal

PYTHONPATH=/workspaces/pants-pythonpath-test hello=123 pants run src:script

Output should be the same as running the python3 command:

PYTHONPATH=/workspaces/pants-pythonpath-test hello=123 python3 src/script.py:

123
/workspaces/pants-pythonpath-test
Now we call the lib
This is from the lib
