Manual Installation problem

[JanosSarkoezi]

Hi picochess developers,

I try to install picochess manualy. Therefore I setup a Dockerfile

FROM ubuntu:18.04
RUN apt-get update && apt-get -y install \
    git \
    vim \
    curl \
    python3 \
    avahi-daemon \
    avahi-discover \
    libnss-mdns \
    espeak \
    festival \
    vorbis-tools \
    sox \
    python3-dev \
    python3-pip \
    libffi-dev \
    libssl-dev \
 && rm -rf /var/lib/apt/lists/*
WORKDIR /opt
RUN git clone --branch master https://github.com/jromang/picochess.git

WORKDIR /opt/picochess

The first problem, if I try (without sudo, because I am root on Docker)

pip3 install --upgrade -r requirements.txt

I get the following error

    ----------------------------------------

As a non python developer I go edit the requirements.txt in the line

python-chess==0.22.1

and change the version from 0.22.1 to 0.23.1. It helps to eliminate this error. It means the command

pip3 install --upgrade -r requirements.txt

runs without an error.

Please help to solve this problem. :)
