Subject of the issue

I get the following error when trying to get list of courses bs4.FeatureNotFound: Couldn't find a tree builder with the features you requested: html5lib. Do you need to install a parser library?

Your environment

  • Operating System: Ubuntu 14.04 LTS
  • Python version: 2.7
  • youtube-dl version: 2017.06.05
  • edx-dl version: 0.1.4

Steps to reproduce

Error occures when I launch the command edx-dl -u a_atef45@yahoo.com --list-course

Expected behaviour

It should gives me list of courses

Actual behaviour

It gives the following

edx_dl version 0.1.4 Password: Building initial headers for future requests. Getting initial CSRF token. Found CSRF token.
