Stories similar to rvm doesn't revert back to system ruby

(Debian squeeze) rvm version: 1.10.0

I have just installed ruby 1.9.2-p290 using "rvm install 1.9.2" and made it default. However, I am getting this error when trying to install rails using rubygems.

According to the official site (http://beginrescueend.com/rubies/default/), the "default" setting of rvm controls the ruby version that is loaded "when you open a new terminal shell".

I am wondering, how exactly does rvm implement this functionality?

So I was making a cgi ruby script and had the following at the top of the script file:

#!/usr/bin/env ruby require 'rubygems' require 'action_pack' require 'cgi'

After a couple of hours of not getting "/usr/bin/env: ruby: No such file or directory" error and google searching, I uninstalled my system ruby 1.8.7 (I also had 1.9.3 installed via rvm) by doing sudo apt-get purge ruby rubygems.

I have been trying to understand RVM and decided to do so by not using it and seeing the consequences. I am trying to see how I can manage different versions of ruby and their gemsets without RVM.

I compiled Ruby 1.9.1 from source on my Ubuntu machine and found it in the path usr/local/bin/ruby.

I am getting the following error when trying to start my Rails application in production for the first time:

/var/www/railsapp/config/initializers/session_store.rb:3: syntax error, unexpected ':', expecting $end ...sion_store :cookie_store, key: '_intranet_session' ^

I have read that this could be an issue with the current ruby version, so I installed RVM and updated the running version.

there is a warning:
