Error while trying to run Sage for the first time

I just installed Sage from pacman. I tried to run it but it spits:

$ sage
┌────────────────────────────────────────────────────────────────────┐
│ SageMath version 7.3, Release Date: 2016-08-04                     │
│ Type "notebook()" for the browser-based notebook interface.        │
│ Type "help()" for help.                                            │
└────────────────────────────────────────────────────────────────────┘
Traceback (most recent call last):
  File "/usr/bin/sage-ipython", line 8, in <module>
    from sage.repl.readline_extra_commands import *
ImportError: No module named sage.repl.readline_extra_commands

Google has not been very useful. Any idea how to fix this?

Have you messed with your python paths? Installed stuff with pip? What's the output of 'which -a python2'?
