Terry J. Reedy <tjre...@udel.edu> added the comment: IDLE uses Python's tcl/tk interface module, called 'tkinter'. Tcl is a separate language and tk is its graphical user interface. This is most likely the problem. Did you follow the advice at https://www.python.org/download/mac/tcltk/ to install tcl/tk 8.5.18? Make sure you read the whole page.
To test better, run 'import tkinter' at Python's interactive '>>>' prompt. Any error message? If that works, run 'python3.6 -m idlelib' and/or 'python -m idlelib.idle' at the terminal '...$' prompt. Does that display an error message? ---------- components: +Installation, macOS nosy: +ned.deily, ronaldoussoren _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue32447> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
