【解决】from win32com.shell import shellcon, shell ImportError: DLL load failed: 找不到指定的程序。
某天用activate myenv激活虚拟环境的时候出现了这个错误。
from win32com.shell import shellcon, shell
ImportError: DLL load failed: 找不到指定的程序。之前都能成功执行。卸载Anaconda重装也无用。
然后发现不管是conda info还是conda env list都会有同样的错误。错误内容如下：
C:\Users\Administrator> conda env list

这些对我都不起作用
【最终解决方案】
从定位上看是pywin32这个库出现了问题，用conda list查看pywin32 显示的版本是223
参考了这个博主的解决办法https://www.cnblogs.com/longweiqiang/p/13086491.html
他说要把pywin32降级到224。
pip install pywin32==224在安装过程中发现，在我的环境中pywin32实际上是227，不是conda list中显示的223。
安装224版本之后，问题解决。
