为什么“pip3 install netifaces"在 Debian 10 Buster 上失败? [英] Why is 'pip3 install netifaces' failing on Debian 10 Buster?

问题描述

我在 AWS EC2 上设置了一个新的 Debian 10 (Buster) 实例，并且能够安装一个依赖于 netifaces 的 pip3 包，但是当我第二天回到它时，该包在 netifaces 中出现了错误.如果我尝试运行 pip3 install netifaces 我得到同样的错误:

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

    AttributeError: 'HTMLParser' object has no attribute 'unescape'

推荐答案

HTMLParser().unescape 在 Python 3.9 中被移除.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 中的一个错误.尝试升级setuptools.或者使用 Python 3.8.

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