I’ve tried a bunch of things to try to install lxml on its own, but to no avail, the error is always the same.
I have the most recent Python version 3.9.6
Does anyone have any idea how to solve this?
Thanks in advance.
Answers:
For some reason was able to install lxml and scrapy outside the virtual environment.
had the same issue in a venv using 3.9; upgraded to 3.10 and it resolved

I’ve tried a bunch of things to try to install lxml on its own, but to no avail, the error is always the same.
I have the most recent Python version 3.9.6
Does anyone have any idea how to solve this?
Thanks in advance.
For some reason was able to install lxml and scrapy outside the virtual environment.
had the same issue in a venv using 3.9; upgraded to 3.10 and it resolved
