Ubuntu 12.0.4 rails was working yesterday. Not today - ruby-on-rails

I use rvm and installed it with this instructions https://rvm.io//rvm/install/.
Yesterday when I was working everything was just fine.
Today when I tried to start rails s it says
The program 'rails' is currently not installed. You can install it by typing:
sudo apt-get install rails
I have no idea how to make it work again. When I run rvm gem list it gives me this:

So does anybody have any idea why the rails stopped working? And I think it has something to do with when I shutdown the computer yesterday.

If you installed it as root, you need to do source /etc/profile.
If you installed it for your own individual user, you should add ~/.rvm/scripts to your $PATH

Gem is in gemlist but getting error: "Could not find gem"

When I try to start my project using rails s I have the following error message occur:
Could not find gem 'jquery-rails (>= 0) ruby' in the gems available on this machine.
Run `bundle install` to install missing gems.
However, I know I definitely have that gem installed because when I put in the command gem list it shows up in my list of gems.

I'm not able to use bundler because the connection is blocked at my workplace, but regardless, why is it giving me the error that the gem needs to be installed when it is installed?
Edit: I used gem environment gemdir to see where my path was for my gems and then tried to set the path for where bundlers looked using bundle config path /installationPath/, but I'm still having the same errors.
Also it is not a problem with the version numbers of the gems in my Gemfile
Bundler messes with the gem load path. gem list shows you what's installed on the system, but not necessarily what Bundler will expose to the application. Have you tried bundle exec rails s or bundle list to see what Bundler is actually exposing?

What do I need to do to get activerecord-import to work?

I am trying to use activerecord-import, but I can't seem to get my application to recognize its existence.
I get
undefined method `supports_import?' for #<Class:...>
or
undefined method `import' for #<Class:...>
no matter what I do. I've been googling this for days and trying everything I can think of
It worked when we had rails 2.3.5 and ar-extensions, but since upgrading to rails 3.2 it has been broken.
Everyone says the solution is to use activerecord-import, but I don't seem to know how to do that. I have installed the gem -- I believe the correct version for my version of ActiveRecord -- and I've required it in my code, but there must be some other thing I have to do.
I have this in my Gemfile:
gem 'activerecord-import', "~> 0.3.0"
this in my code:
require 'activerecord-import'
and this is my gem list:

The answer is that there are some special steps you need to take to use this particular gem.
require "activerecord-import/base"
ActiveRecord::Import.require_adapter('mysql2')
This was found on the github wiki page for activerecord-import

Why is Rubygems not able to install Rails?

I am trying to install rails using the command
gem install rails
on my ubuntu 12.04 . Also I have configured my apt.conf file with the username , password and proxy details . Then too the execution of this command gives an error as :
ERROR: While executing gem ... (Net::HTTPServerException)
407 "Proxy Authentication Required"
If I run
sudo gem install rails
the errors are :
ERROR: While executing gem ... (Gem::DependencyError)

I have already run "rvm requirements" and I have tried using SET HTTP_PROXY but it also doesn't have any affect . What should I do ?
EDIT:
I tried using
export http_proxy=http://${username}:${password}#${proxy}:${port}
and then ran gem install rails and it worked ...
super user and normal user has different gem list.
I think super user does not have polyglot and tilt.
Try:
sudo gem install polyglot
sudo gem install tilt
Please check gem list of super user.
sudo gem list

warble, cannot load such file -- spec/rake/spectask error

I'm very new to Ruby, Jruby and Rails etc. I'm trying to deploy a jruby application to tomcat server using warble. I'm on a windows machine, below is the error I get when I run warble from the project's root directory. I did google a lot for the issue, but either the solution didn't work or it wasn't detailed enough for a newbie to understand. Any help or advice is highly appreciated.

Add this to the bottom of your ~/.bashrc file:
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"
If that doesn't work try:
[[ -s "/home/yourusername/.rvm/scripts/rvm" ]] && source "/home/yourusername/.rvm/scripts/rvm"
Terminal->Edit->Profile Preferences->Title and Command->Run command as a login shell
I guess you need edit ur terminal settings
just try
https://beatreader.wordpress.com/2016/08/09/ruby-on-rails-problemmissing-after-reboot/
or
You need to run this code everytime you open for terminal
source "$HOME/.rvm/scripts/rvm"
