"listen" conflict when installing Jekyll with Docker

I am trying to install Jekyll in a Dockerfile extending the Jenkins official image (2.19.1)

The following commands :

RUN apt-get install -y ruby-full rubygems
RUN gem install jekyll

produce the following error :

Step 2 : RUN gem install jekyll

Has anyone faced the same error ? How to fix ? Thanks.

The error is due to a bad ruby version for listen :

IMPORTANT: Ruby 2.1 is officially outdated and unsupported! Please upgrade to Ruby 2.2.5 before installing Listen!

The ruby version installed by the package manager is ruby-2.1. So I ended up installing Ruby via RVM :

RUN gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3 \
    && curl -sSL https://get.rvm.io | bash -s stable --ruby --gems=jekyll

It installs ruby-2.3 and jekyll and it works like a charm.
