0 写在前面

环境：

• mac catalina 10.15.1
• python 3.7.5
• tkinter 8.6

1 问题描述

运行如下demo时，

import tkinter as tk # Python 3.x Version
root = tk.Tk()

label = tk.Label(root, text="Hello 世界!") # Create a text label
label.pack(padx=20, pady=20) # Pack it into the window

root.mainloop()

可能会出现如下问题，

The system version of Tk is deprecated and may be removed in a future release. Please don't rely on it. Set TK SILENCE DEPRECATION=1 to suppress this warning.

这是因为版本和mac自带的tcl/tk版本不对应造成的，对应版本参考链接1

1 解决办法

对于homebrew安装的python3，以下命令不再支持

brew install python3 --with-tcl-tk

也有如下方法

brew install tcl-tk

或者直接去下载avtiveTcl的，但是下载之后python3还是会连接mac系统(catalina 10.15.1)自带的tcl8.5版本

于是费了九牛二虎之力终于找到解决方法

1.1 首先确保卸载python3

brew uninstall python3
brew cleanup

1.2 然后安装xcode

xcode-select --install
brew update

1.3 替换ruby脚本

将“/usr/local/Homebrew/Library/Taps/homebrew/homebrew-core/Formula/python.rb”路径下的脚本替换为如下，记得备份

以上是安装的python3.7.5，针对不同版本例如版本3.7.4，首先替换第4行的url

url "https://www.python.org/ftp/python/3.7.5/Python-3.7.5.tar.xz"
url "https://www.python.org/ftp/python/3.7.4/Python-3.7.4.tar.xz"//针对python3.7.4

然后输入上面网址"https://www.python.org/ftp/python/3.7.4/Python-3.7.4.tar.xz"下载xz文件到桌面，

然后终端运行如下就能获取匹配相应python版本的sha256值

openssl dgst -sha256 /Desktop/Python-3.7.4.tar.xz

然后替换第5行的sha256 "e85a76ea9f3d6c485ec1780fca4e500725a4a7bbc63c78ebc44170de9b619d94"就行了

1.4 安装 python

终端输入如下命令，等待安装完成即可

HOMEBREW_NO_AUTO_UPDATE=1 brew install --build-from-source python

1.5 检验

首先记得设置brew安装的python默认路径，然后终端因此输入如下命令

python3
import tkinter
tkinter.TkVersion

就能看到输出python3对应的tcl8.6版本啦
