also not able start webrick server using radrails. server in stopped state , console output blank. not able fix since dont see errors.

thank you!

use rvm or rbenv change ruby , gem space one. if begin usage of them following:

1. install rvm ruby:

   $ \curl -ssl https://get.rvm.io | bash -s stable --ruby 

   or install rbenv, , install ruby, , make global:

   $ \curl https://raw.githubusercontent.com/fesplugas/rbenv-installer/master/bin/rbenv-installer | bash $ rbenv install 2.1.4 $ rbenv global 2.1.4 

2. install rails without documentation general gem space:

   $ gem install rails --no-ri --no-rdoc 

3. enter project, create 2 files .ruby-version installed version of ruby (in example 2.1.4), , .ruby-gemset name of project:

   $ cd project-folder $ echo "2.1.4" > .ruby-version $ echo "your-project-name" .ruby-gemset 

4. fix gemfile newly intsalled version of ruby adding line:

   ruby '2.1.4' 

5. reenter project folder, , rvm generate wrappers:

   $ cd .. ; cd project-folder 

6. issue gem installation:

   $ bundle install
