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, shellImportError: 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：

github上的解决方案：
/ContinuumIO/anaconda-issues/issues/11752
/conda/conda/issues/9356#issuecomment-577271046
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/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。
