`Command /usr/bin/python3 -c "import setuptools, tokenize;file='/tmp/pip-build-vhc0qtab/bcrypt/setup.py';exec(compile(getattr(tokenize, 'open', open)(file).read().replace('\r\n', '\n'), file, 'exec'))" install --record /tmp/pip-v9cb4je7-record/install-record.txt --single-version-externally-managed --compile --user failed with error code 1 in /tmp/pip-build-vhc0qtab/bcrypt Storing debug log for failure in /home/vkristof/.pip/pip.log

Answer 1

one of the error messages states, that libffi is missing. on a debian-like system you could try $ sudo apt-get install libffi6 libffi-dev.
