Python3 cannot install bcrypt

Question

When I try to install bcrypt, python3 -m pip install bcrypt,

I get the following:

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

Answer 1

one of the error messages indicates that libffi is missing. on a similar debian system you can try $ sudo apt-get install libffi6 libffi-dev.
