maybe the problem is not with this repository but with the dependent module :

The problem is indeed with the dependent module

I couldn't get it working on alpine based docker images. It seems to work when using a debian based docker image (e.g. node:16-buster-slim)

FYI I have created myself a number of node-red docker images based on debian which you can find at following location:

I am using the following base image in my docker container

I also had to add the following lines to my dockerfile to get it working:

# fix missing libxml2 and libc.musl-x86_64.so.1 (see https://github.com/alexander-akhmetov/python-telegram/issues/3)  and
USER root
RUN apt-get update && apt-get install -y musl-dev libxml2
RUN ln -s /usr/lib/x86_64-linux-musl/libc.so /lib/libc.musl-x86_64.so.1
USER node-red
# end of fix
