tried
sudo apt-get remove build-essential libffi-dev python-dev
sudo apt-get install build-essential libffi-dev python-dev

Check what version of pycparser you have installed as root vs the version in your jenkins virtualenv. That may be the issue.

solved it by

pip uninstall  bcrypt cffi pycparser
pip install --user --upgrade cffi
pip install --user --upgrade bcrypt
