Passei por alguns tutoriais sobre como instalar o Ruby 2.1.* Meu sistema atualmente tem o Ruby 1.9.3 e quero o mais recente. Estou seguindo o seguinte tutorial sobre como instalá-lo aqui:http://ryanbigg.com/2014/10/ubuntu-ruby-ruby-install-chruby-and-you//
Até agora, estes são os comandos que fiz:
sudo apt-get install build-essential
wget -O ruby-install-0.5.0.tar.gz \
https://github.com/postmodern/ruby-install/archive/v0.5.0.tar.gz
tar -xzvf ruby-install-0.5.0.tar.gz
cd ruby-install-0.5.0/
sudo make install
ruby-install ruby 2.1.3
DEPENDENCY ERRORS
Assim que consigo instalar o Ruby Ruby 2.1.3, recebo o seguinte:

Ok, diz que estou perdendo todas essas dependências. Como posso fazer com que eles o instalem para que ele pare de reclamar? Por que não existe um comando que diz apenas "ok, você está perdendo essas dependências, deixe-me instalá-las para você (sim/não)?

A seguir estão os comandos para instalar Ruby 2.1 em um sistema baseado em Debian de acordo com o oficialArquivo Docker Ruby. Aliás, você pode evitar essa dor usando o Docker.
# Update your system packages
apt-get update
# Install some basic dependencies
# Few of thems aren't needed but won't hurt anyway
apt-get install -y \
autoconf \
build-essential \
imagemagick \
libbz2-dev \
libcurl4-openssl-dev \
libevent-dev \
libffi-dev \
libglib2.0-dev \
libjpeg-dev \
libmagickcore-dev \
libmagickwand-dev \
libmysqlclient-dev \
libncurses-dev \
libpq-dev \
libreadline-dev \
libsqlite3-dev \
libssl-dev \
libxml2-dev \
libxslt-dev \
libyaml-dev \
zlib1g-dev \
apt-get install -y curl procps
RUBY_MAJOR="2.1"
RUBY_VERSION="2.1.5"
apt-get install -y bison ruby
mkdir -p /usr/src/ruby
curl -SL "http://cache.ruby-lang.org/pub/ruby/$RUBY_MAJOR/ruby-$RUBY_VERSION.tar.bz2" | tar -xjC /usr/src/ruby --strip-components=1
cd /usr/src/ruby
autoconf
./configure --disable-install-doc
make -j"$(nproc)"
apt-get purge -y --auto-remove bison ruby
make install
rm -r /usr/src/ruby
GEM_HOME="/usr/local/bundle"
PATH=$PATH:$GEM_HOME/bin
gem install bundler
bundle config --global path "$GEM_HOME"
bundle config --global bin "$GEM_HOME/bin"
Como você pode imaginar, alguns dos comandos precisarão ser inseridos no modo sudo.
Neste ponto você deve ter o Ruby 2.1.5 instalado. Para verificar digite ruby -v.
NOTA: Eu não testei isso, então fique à vontade para trazer comentários.
