问题
My environment:
macOS 10.13 python 3.7.1 from Homebrew
I'm having lots of Tcl/TK quirks on the stock Tcl/TK 8.5 under /System/Library/Frameworks/Tcl.framework/Versions/8.5/, and would like to upgrade my Tcl/TK.
But with this question I couldn't find any working tips for upgrading, including:
https://discussions.apple.com/thread/8066794 IDLE warns against an old TCL version even though I've installed a newer version Why my Python installed via home brew not include Tkinter How to change the tk version of your Python installation? How do I link the ActiveState distribution of Tcl/Tk to HomeBrew installed Python
My test results
--with-tcl-tkno longer works with the latest Homebrew. Runningbrew install python --with-tcl-tkstill points to system Tcl/TK 8.5.9.- The above is also tested with an uninstall/install cycle.
- Python keeps using system Tcl/TK after installing latest ActiveTcl.
回答1:
After many more failures, I concluded that the easiest way to make this work is to completely forget about Homebrew, uninstall its python packages.
Then install the latest ActiveTcl and then the python.org version instead. The python.org version will work on top of the latest "System" Tcl/TK, which will be refreshed after installing the ActiveTcl. Unfortunately, Homebrew ignores it.
The current 3.7.2 from python.org is compiled with Tcl/TK 8.6.8:
$ python3
Python 3.7.2 (v3.7.2:9a3ffc0492, Dec 24 2018, 02:44:43)
[Clang 6.0 (clang-600.0.57)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import tkinter as tk
>>> print(tk.Tcl().eval('info patchlevel'))
8.6.8
After updating it, several bugs like checkbuttons showing wrong checkmarks on a menu disappeared.
