I am trying to access the console to manage my application and it wont let me. what i right is rails console or rails c and i get this:

agustin@agustin:~/Agustin/RoRProyect$ rails c
/usr/lib/ruby/vendor_ruby/active_support/test_case.rb:12:in `<module:ActiveSupport>': uninitialized constant Test (NameError)
    from /usr/lib/ruby/vendor_ruby/active_support/test_case.rb:11:in `<top (required)>'
    from /usr/lib/ruby/vendor_ruby/rails/console/app.rb:2:in `<top (required)>'
    from /usr/lib/ruby/vendor_ruby/rails/application.rb:312:in `initialize_console'
    from /usr/lib/ruby/vendor_ruby/rails/application.rb:152:in `load_console'
    from /usr/lib/ruby/vendor_ruby/rails/commands/console.rb:27:in `start'
    from /usr/lib/ruby/vendor_ruby/rails/commands/console.rb:8:in `start'
    from /usr/lib/ruby/vendor_ruby/rails/commands.rb:41:in `<top (required)>'
    from script/rails:6:in `require'

Answer 1

It's a bug and described here .

Run these following commands :

sudo apt-get install ruby-test-unit
sudo echo require 'test/unit' >> /usr/lib/ruby/vendor_ruby/active_support/test_case.rb

And I think using RVM or RBENV is a popular practice amongst the Ruby Community to install and maintain ruby versions.

Install Ruby using RVM :

Make sure you have logged in using shell:

Terminal > Edit > Profile Preferences > Title and Command > Check Run command as a login shell

Install depencies:

sudo apt-get install git-core curl zlib1g-dev build-essential libssl-dev libreadline-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt1-dev libcurl4-openssl-dev python-software-properties

Install RVM and Ruby 2.1.5

sudo apt-get install libgdbm-dev libncurses5-dev automake libtool bison libffi-dev
curl -L https://get.rvm.io | bash -s stable
source ~/.rvm/scripts/rvm
echo "source ~/.rvm/scripts/rvm" >> ~/.bashrc
rvm install 2.1.5
rvm use 2.1.5 --default
ruby -v

To exclude documentation for each package:

echo "gem: --no-ri --no-rdoc" > ~/.gemrc

Before installing rails you can install node which will come along the v8 JS engine:

sudo add-apt-repository ppa:chris-lea/node.js
sudo apt-get update
sudo apt-get install nodejs

Finally rails (optional) :

gem install rails
