missing read().encode('utf-8') > convert to bytes :)

This issue was fixed once before in PR #9 and then reverted in 02c2006

A work-around I found is to set the system locale to UTF-8. For example, when using Docker with the Ubuntu base image, the locale is not set by default and this error comes up when trying to install this module. Add these commands to the Dockerfile to work around this (found here):

RUN locale-gen en_US.UTF-8
ENV LANG en_US.UTF-8
ENV LANGUAGE en_US:en

Or, if not using Docker just run the commands at the shell (and look into how to set them permanently so they persist on reboot, e.g. Ubuntu Locale):

root# locale-gen en_US.UTF-8
root# export LANG en_US.UTF-8
root# export LANGUAGE en_US:en

I had the same error, changing line 7 in setup.py to
long_description=open('README.md', 'r', encoding='utf-8').read() fixed it for me.

Can I give a pull request with @grimlaufer's solution? I am also facing this issue.

[marceltschoppch]

I just added a pull request with the solution from @grimlaufer, slightly adjusted to not break environments with python < 3.0

Sorry i know this is old thread but if you are using Docker container assuming you are doing something like this

RUN yum -y update
RUN yum -y install epel-release
RUN yum -y install centos-release-scl centos-release-scl-rh
RUN yum -y install git
RUN yum -y install python36 rh-python36-python rh-python36-python-pip rh-python36-python-virtualenv

Make sure you add your ENV after the above

RUN localedef -i en_US -f UTF-8 C.UTF-8 
ENV LANG="C.UTF-8"
ENV LC_LANG="C.UTF-8"
