为什么在Debian 10 Buster上'pip3 install netifaces'失败?

问题描述

我在AWS EC2上设置了一个新的Debian 10(Buster)实例，并且能够安装依赖于netifaces的pip3软件包，但是第二天我回到它时，该软件包中断了，报告了netifaces中的错误.如果我尝试运行pip3 install netifaces，则会收到相同的错误:

I setup a new Debian 10 (Buster) instance on AWS EC2, and was able to install a pip3 package that depended on netifaces, but when I came back to it the next day the package is breaking reporting an error in netifaces. If I try to run pip3 install netifaces I get the same error:

~$ pip3 install netifaces

        unescape = getattr(html, 'unescape', html_parser.HTMLParser().unescape)
    AttributeError: 'HTMLParser' object has no attribute 'unescape'

推荐答案

HTMLParser().unescape 在Python 3.9中已删除.比较 Python 3.8中的代码与 Python 3.9 .

HTMLParser().unescape was removed in Python 3.9. Compare the code in Python 3.8 vs Python 3.9.

该错误似乎是 setuptools 中的错误.尝试升级 setuptools .或使用Python 3.8.

The error seems to be a bug in setuptools. Try to upgrade setuptools. Or use Python 3.8.
