  angr has transitioned to python 3. Due to the small size of the team behind it,
  we can't reasonably maintain compatibility between both python 2 and python 3.
  If you want to continue using the most recent version of angr (you definitely
  want that, trust us) you should upgrade to python 3. It's like getting your
  vaccinations. It hurts a little bit initially but in the end it's worth it.
  
  For more information, see here: https://docs.angr.io/MIGRATION.html
  
  Good luck!
