Installing Ruby and Hobo on a fresh Ubuntu Machine

This way several ruby versions can be installed individually and it's easy to switch between them.

Installing prerequesties

sudo apt-get install bash curl git-core build-essential bison openssl libreadline6 libreadline6-dev zlib1g zlib1g-dev libssl-dev libsqlite3-0 libsqlite3-dev sqlite3 libxml2-dev curl git-core libyaml-dev libxslt-dev autoconf libmysqlclient-dev libreadline5 libltdl-dev libncurses5-dev libserf1-dbg libsvn1 libtool subversion libgdbm-dev pkg-config libffi-dev@

Installation rvm (Ruby Version Manager): Be sure to switch to the user you want to use this Ruby with. Rubies are installed on a per user basis.

bash -s stable < <(curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer)

Append the following to your .bashrc-File, that is located ad /home/«YOUR_USER_NAME»/.bashrc That's done easiest with nano ~/.bashrc, because nano gives you help to store, leave, etc. at the bottom line, when started

@source /home/%USER%/.rvm/scripts/rvm@

To test, if everything's fine close your terminal and start a new one and test

@type rvm | head -n1@

The output has to be rvm is a function (or a translated version of that text). Otherwise something went wrong.

To let rvm install missing libraries in the future automatically (this is an optional step)

rvm autolibs 3

Install the latest ruby

rvm install ruby

To install latest hobo

gem install hobo

A fitting rails version is installed automatically. You are done!

Tips

Install a certain ruby version (e.g.)

rvm install ruby-2.1.5

To select a ruby as default

rvm --default use 2.1.5

To use a ruby just for this session

rvm use 2.1.5

Check which rubies are installed

rvm list rubies

Check which rubies rvm can install

rvm list known
