Hello @Taibah

Maybe you are using python2 when you need python3.
Make sure you are using a virtualenv as explained in the recommendations here: https://github.com/blockchain-certificates/cert-issuer/blob/master/docs/virtualenv.md

I saw a similar error here: Error installing cert-issuer on ethereum (which I think could have been solved by installing python3-dev).
