Cryptacular is broken

Question

this weekend our docker image broke because it cannot be build anymore. While looking into the stats, I saw this line:

crypt_blowfish-1.2/crypt.h:17:23: fatal error: gnu-crypt.h: No such file or directory

In more detail:

  Failed building wheel for cryptacular
  Running setup.py clean for cryptacular

Our implementation works with the package cryptacular which uses bcrypt. None of the packages were updated last week and I dont know where to start.

As additional information, the error occurs in this block of our Dockerfile

RUN apt-get install -y build-essential libfontconfig && \
    pip install -q -U pip && \
    pip install -q -r requirements.txt && \
    apt-get remove -y --purge build-essential && \
    apt-get autoremove -y && \
    apt-get clean -y

where the requirements.txt uses cryptacular==1.4.1

Edit: We are working with the python:3.6-slim image

Sweven

Do you have install the glibc and glibc-dev? – Pyrazole

Yeah, build-essential are installed. – Sweven

See bitbucket.org/dholth/cryptacular/issues/11/… – Orthopedics

Answer 1

We don't know the error exactly, but last weekend there was an security update in the base image. Therefore we pinned our python image to 3.6.4.

Answer 2

I had the same issue running python 3.6.6. With this one liner I was able to install cryptacular from the latest commit.

pipenv install -e hg+https://bitbucket.org/dholth/cryptacular@cb96fb3#egg=cryptacular

You will need to have mercurial installed

apt-get update && apt-get install -y mercurial

Answer 4

My problem solved by install cryptacular before install apex

Answer 5

On Gentoo:

pip3 install -e hg+https://bitbucket.org/dholth/cryptacular@cb96fb3#egg=cryptacular --user

--user flag is required and I didn't have pipenv.

Version: pip 20.0.2 from /usr/lib/python3.7/site-packages/pip (python 3.7)
