如何解决导入skimage时报DLL加载失败的ImportError错误？

ImportError: DLL load failed while importing _rolling_ball_cy: The specified module could not be found.

这是Windows平台下scikit-image库的典型DLL依赖问题，常见于Python 3.9环境安装0.19.x版本的skimage时：要么是预编译的扩展包依赖的VC++运行时组件与系统环境不匹配，要么是包文件下载过程中出现损坏，导致cython编译的_rolling_ball_cy扩展模块无法加载对应的动态链接库。

• 第一步：卸载当前已安装的损坏版本
  执行命令：pip uninstall scikit-image -y
• 第二步：选择对应场景的方案重新安装
  • 普通pip环境优先选该方案：安装经过验证的稳定兼容版本
    执行命令：pip install scikit-image==0.18.3
  • 需要使用最新版skimage的场景：先安装微软VC++ 2015-2022可再发行运行库，重启终端后执行命令安装最新版：pip install scikit-image
  • conda环境用户直接使用conda安装，会自动补全所有DLL依赖：conda install scikit-image
• 第三步：验证修复效果
  执行代码from skimage.segmentation import clear_border，无报错即为修复完成。
