My Idle (idle3) from python installed with homebrew on a mac crashes

Question

Idle3 (of python3) regularly crashes when in a window and using the middle mousewheel.

There is always the same error left in Terminal:

Traceback

Answer 1

The problem seems to be that brew installed python without tcl-tk, thus using the old tcl-tk from mac-os. This one has a problem interpreting some mousewheel commands.

The solution : brew reinstall python --with-tcl-tk
