ImportError: DLL load failed while importing shell: The specified procedure could not be found.

conda 环境中安装的包依赖了 pywin32 时，运行代码会出现“ImportError: DLL load failed while importing shell: The specified procedure could not be found.”异常。

例如：

需要将 conda 环境目录下“Lib\site-packages\pywin32_system32\”下的所有 dll 文件复制到 “Library\bin\” 下。

查看 conda 环境目录路径可以通过 “conda info -e” 来看。不过需要在 base 环境下看，因为 info 命令会调用 pywin32 库，不在 base 环境下有可能会遇到出错。
