I’ve done a little bit of debugging and have a workaround that should result in a mostly-functioning angr environment. Checkout unicorn from git, and follow their *nix build instructions, outside of a virtualenv, with python2 as python. Then, after that build is complete, activate your python3 virtualenv, and cd into the bindings/python directory. Then run python setup.py install. Now unicorn is installed, run pip install angr. It’ll take a while because it has to build everything, but it should succeed and you should be able to use angr.

A decent fix should be underway, a PR has been submitted to unicorn: https://github.com/unicorn-engine/unicorn/pull/1107

Once that is merged I believe the intent is to make at least a pip release which should make more people’s lives easier.
