Could you help to solve this problem?

OS X EI Captain 10.11.6

Answer 1

You appear to be using Python 3. angr depends upon the package dpkt-fix, which tries to import itself when installing, which fails in Python 3 because dpkt-fix's code uses import ah (et alii) to mean import .ah, which only works in Python 2.

Solution: Use Python 2 instead.
