Answer 1

Yesterday i upgraded to Python 3.9 and the pip install lxml also failed. But i managers to install it from a downloaded whl file. Can not remember from where i downloaded it, but you should be avle to find the answer somewhere on stackoverflow. The lxml package installation seems to work fine for me with bs4

Maybe it was from here: https://www.lfd.uci.edu/~gohlke/pythonlibs/

lxml‑4.5.2‑cp39‑cp39‑win_amd64.whl <---
