Sagemath does not open anymore

edit

I was trying to install sagemath-jupyter on my Arch Linux (which turned out to be a near impossible task) and deleted a bunch of packages from pip2. Now I can't even open sagemath, even after re-installing sagemath from Pacman:

Traceback (most recent call last):

    from ipython_genutils.py3compat import cast_bytes_py2
ImportError: No module named ipython_genutils.py3compat

Any ideas on how to overcome this? (And preferably also installing sagemath-jupyter?

I have installed ipython_genutils with pip2 already (version 0.1.0).
