python - 如何解决 python 人性化错误：ImportError cannot import name on_windows from 'humanfriendly.compat'

问题描述

我在 Windows 10 上并使用 python 3.7.3

如果我打开一个 ipython 终端并输入：

import humanfriendly

我收到以下错误：

        In [7]: import humanfriendly
---------------------------------------------------------------------------

---> 45 from humanfriendly.compat import coerce_string, is_unicode, on_windows, which
     46 from humanfriendly.decorators import cached
     47 from humanfriendly.deprecation import define_aliases

ImportError: cannot import name 'on_windows' from 'humanfriendly.compat' (C:\Users\Me\Anaconda3\lib\site-packages\humanfriendly\compat.py)

我在 google 或 StackOverflow 上找不到与此错误消息特别相关的任何内容。

如何解决此错误？

解决方案

最终将问题追溯到不包含“on_windows”功能的 Anaconda 版本的humanfriendly。conda-forge 版本可以。

我用了

conda remove humanfriendly

然后

conda install --channel "conda-forge" humanfriendly

问题解决了。
