先说踩坑点

各种模块缺失

tkinter

mysql

没错，你可以直接点击安装；

请添加图片描述

如果还出现报错
请添加图片描述

你需要打开终端

pip install mysqlclient

再次点进去安装后会出现导包，选择第二个

同样在这个页面，搜索安装各种模块

docx

报错

“Traceback (most recent call last):File "/Users/lin/Desktop/Python/mysql/tomd.py", line 4, in <module>from docx import Document”

请添加图片描述

但是这里又出现了一个问题

由于我是使用anaconda的python环境

需要更换为本地的安装的python3.11
请添加图片描述

我还是使用之前项目的3.11（同一个版本），换了之后同样出现tk无法查找模块的话

先查找本机python匹配的版本

brew search python-tk
==> Formulae
python-tk@3.10     python-tk@3.9       python@3.7          python@3.9 
python-tk@3.11      python-yq           python@3.8

最后安装

brew install python-tk@3.11

最后安装tkinterMessagebox，安装好后如下图

请添加图片描述
