I don't know how to resolve this issue. I tried to install other xmlsec package too, nothing worked.

Answer 1

Xmlsec listed here https://pypi.org/project/xmlsec/. The below command should install for download required native libraries.

sudo apt-get install pkg-config libxml2-dev libxmlsec1-dev libxmlsec1-openssl

Answer 2

I had a similar issue with installing xmlsec. What did it for me was reinstalling the required native libraries listed here: https://pypi.org/project/xmlsec/

It was as simple as installing: brew install libxml2 libxmlsec1 pkg-config
