Can’t install xmlsec using PIP command

pip install xmlsec commands throws the below error.

ERROR: Command errored out with exit status 1:

  ERROR: Failed building wheel for xmlsec
Failed to build xmlsec
ERROR: Could not build wheels for xmlsec which use PEP 517 and cannot be installed directly'

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

Answer

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
