This bug has already been fixed on the master branch. Either install angr from Github (use the angr-dev repo for an install script) or wait for the next release.

Thank you for your prompt reply!!
You mean I should reinstall angr && angrop?
I'm also using your MechPhish(Driller, Rex, etc), so which version would you recommand?

[rhelmot]

I do mean that you should reinstall angr, via my explanation above. Your current versions of the mechaphish components should be fine.

Thank you!! I solved the problem by reinstalling angr.

The following code is written for anyone with the same problem as me.
It will help them fix the problem.

pip uninstall angr
pip install git+https://github.com/angr/angr.git

[rhelmot]

For anyone else who encounters this problem in the future: do not do that, you will be mixing versions of the angr libraries from pip and github, which is a recipe for disaster. Do this:

pip uninstall angr cle claripy pyvex archinfo
git clone https://github.com/angr/angr-dev
cd angr-dev
./setup.sh
