Wing Pro 6.1.0-1 (rev 7089881dae36)I have a couple of environment variables that I want to use as my custom Python Path.I chose Custom under Project Properties → Python Path and set its value to: $FIRST_VAR:$SECOND_VARâ Each one of these variables has a colon-separated list of paths (all valid). However, when I click Apply, I get an error message:Some property warnings were encountered:- PYTHONPATH entry 'path1:path2:path3' does not exist or cannot be found- PYTHONPATH entry 'path4:path5' does not exist or cannot be foundWhat could be causing this and how do I fix it?UPDATE: This used to work in Wing Pro 5.x
