我在windows 10上，使用python 3.7.3
如果我打开一个ipython终端并键入：
import humanfriendly
我得到以下错误：
In [7]: import humanfriendly

ImportError: cannot import name 'on_windows' from 'humanfriendly.compat' (C:UsersMeAnaconda3libsite-packageshumanfriendlycompat.py)
我在谷歌或StackOverflow上找不到任何与此错误消息相关的内容。
如何解决此错误？
最终将问题追溯到Anaconda版本的人性化，该版本不包括'on_windows'功能。conda-forge版本确实如此。
我使用
conda remove humanfriendly
然后
conda install --channel "conda-forge" humanfriendly
问题解决了。
