Windows10下VSCode运行customtkinter代码提示packaging模块缺失

问题描述 #

在Windows 10系统的VSCode中运行包含customtkinter的Python代码时，出现以下错误：

解决方案 #

• 步骤1：确认VSCode使用的Python解释器
  点击VSCode右下角显示的Python版本，选择你正在使用的解释器路径：C:\Users\dbrav\pyver\py3121\python.exe，确保代码运行环境和安装包的环境一致。

• 步骤2：安装缺失的packaging模块
  打开VSCode终端，执行以下命令（用对应环境的pip）：

  C:\Users\dbrav\pyver\py3121\Scripts\pip.exe install packaging
  

  如果终端已经激活该Python环境，直接运行：

  pip install packaging
  

• 步骤3：（可选）重新安装customtkinter确保依赖完整
  如果安装packaging后仍有问题，强制重新安装customtkinter到当前环境：

  C:\Users\dbrav\pyver\py3121\Scripts\pip.exe install --force-reinstall customtkinter
