ykman installation

I tried installing ykman in ubuntu-18.04(WSL) using below commands,

sudo apt-add-repository ppa:yubico/stable sudo apt update sudo apt install yubikey-manager 

when I try to find the version using: ykman --version. I'm getting an error like,

Traceback (most recent call last): File "/usr/bin/ykman", line 6, in <module> from pkg_resources import load_entry_point ModuleNotFoundError: No module named 'pkg_resources' 

Please anyone help with this
