我试图安装BeautifulSoup4以学习网络抓取。我使用pip为Python 3.10安装bs4包，但我无法安装它。任何帮助都可以解决以下回溯错误。注意：我使用的是WSL2 Ubuntu 20.04

Answer 2

BS4发布于2021年9月8日https://pypi.org/project/beautifulsoup4/#history

Python3.10 realease in：2021年10月4日https://devguide.python.org/#status-python分支

在BS4更新之前，我认为存在兼容性问题。

在那之前，一切都应该用3.9，所以我会用它。
