I installed Ruby and Rails in Ubuntu(Guest OS) which is mounted on Windows (Host OS) using Virtual Box. But every time I reboot Guest OS, I need to re install Ruby on Rails.I have some experience with Virtualbox & Ubuntu.

Even after installing ruby and rails in same same session(without rebooting guest OS) if I open a different terminal and type ruby --version or irb commands it asks me to install ruby using sudo apt-get install .

How can I solve this install Ruby and Rails permanently in Ubuntu (Guest OS) ? Thanks in advance.

Do you installed ruby via apt-get or gem? –  muniz95 Mar 13 at 20:32

Set your ruby version to 2.0.0 typing rvm use '2.0.0' --install. Then, type gem install rails, and open a different terminal to test the persistence. –  muniz95 Mar 13 at 20:40
