Matplotlib导入错误：导入_cext时DLL加载失败求助

错误信息如下：

解决步骤： #

• 重新安装kiwisolver
  打开命令提示符，执行以下命令彻底卸载并重新安装：

  pip uninstall kiwisolver -y
  pip install kiwisolver
  

  若pip与Python解释器路径不匹配，改用python -m pip确保使用当前环境的包管理器：

  python -m pip uninstall kiwisolver -y
  python -m pip install kiwisolver
  

• 安装对应版本的kiwisolver wheel包
  如果直接pip安装无效，下载与你的Python版本（3.11）、系统架构（x64）匹配的kiwisolver wheel文件，然后本地安装：

  pip install path/to/kiwisolver-xxx-cp311-cp311-win_amd64.whl
  

• 安装Visual C++ Redistributable
  kiwisolver的C扩展依赖微软Visual C++运行库，下载并安装适用于Windows x64的VS 2015-2022版本运行库，安装完成后重启Python环境再测试。

• 验证Python环境一致性
  执行where python查看当前运行脚本的Python路径，再执行pip --version确认pip对应的Python路径是否一致，避免因多环境导致的包安装错位。
