I'm trying to install pendulum 2.0.5 in a python37-alpine based docker image but it gives me the below error:

Initially, I was able to install and get it working for about a week but yesterday I tried to rebuild the docker image again and it's failing.
Here's my Dockerfile:
FROM python:3.7-alpine
# Install nodejs, npm and vim
RUN apk add --update --no-cache nodejs npm vim curl
# To handle 'not get uid/gid'
RUN npm config set unsafe-perm true
# install serverless framework
RUN npm install -g serverless@${SLS_VERSION}
# install base dependencies
RUN apk add --no-cache build-base \
&& pip install pipenv awscli
# change work directory
WORKDIR /app
# Copy NPM dependencies files
ADD package.json package-lock.json ./
# install serverless dependencies
RUN npm install
# Copy python dependencies file
ADD Pipfile Pipfile.lock ./
# install python dependencies
RUN pipenv install --system --deploy --ignore-pipfile --dev
ADD docker-init.sh .
# Expose the ports to host
EXPOSE 3000 4000 4001
Any help is appreciated.
You need to install libffi-dev and probably openssl-dev as well (plus a C compiler if you don't have one available) because cffi and cryptography require these packages to compile against system libraries. Normally these packages have binary wheels available, but Alpine uses a different libc which is incompatible with the manylinux specification so you'll have to compile it yourself.
Update: As of 2022 cryptography ships musllinux wheels which are compatible with Alpine. To get them, ensure you're running the latest pip version and are installing cryptography 35.0 or newer (you should always try to run the latest version!).
