conda安装scikit-learn报错

在win7下安装scikit-learn会报错

ERROR conda.core.link:_execute(701): An error occurred while installing package 'defaults::scikit-learn-1.0.1-py37hf11a4ad_0'.
Rolling back transaction: done

LinkError: post-link script failed for package defaults::scikit-learn-1.0.1-py37hf11a4ad_0
location of failed script: E:\PPY\Scripts\.scikit-learn-post-link.bat
==> script messages <==

这里应该是conda的源导致的问题，解决方法可以使用下面的命令安装

conda install -c anaconda scikit-learn
