Dear Catalyst Maintainers,

Pip install seems to be broken

I am trying to install a fresh virtualenv for Catalyst on Ubuntu 16.04. When I do pip install enigma-catalyst matplotlib, I get the following error:

What steps have you taken to resolve this already?

I am still investigating the issue. Apparently it is related to web3==4.0.0b7 and it requires Pandoc also, which is not listed among the OS requirements. You might want to list that also as a requisite if you are able to reproduce the error.

Sincerely, V
