I setup a new rail application in Netbeans 7.1. Without writing any code, I wanted to see if it just runs but

When clicking run I get errors:

I've installed a few gems it was complaining about through netbeans gem manager but I got stuck at mysql2. Even though I installed mysql and mysql2 gems, it still won't find it.

With little research, it seems i have to do a bundle install, for WEBrick to run/ check dependencies or whatever. Netbeans project has a Bundler context menu with options for check, init, install, show etc.

None of those produce any output in the Output: Bundler window. The Bundler process starts in netbeans processes but then quits after a second. No errors, info or anything.

What do I need to do to get this working. This is a blank Ruby/Rails Application through Netbeans 7.1.

EDIT 1: The error in file: C:/Ruby193/lib/ruby/gems/1.9.1/gems/mysql2-0.3.11-x86-mingw32/lib/mysql2/mysql2.rb:2 contains the following lines: 

RUBY_VERSION =~ /(\d+.\d+)/
require "mysql2/#{$1}/mysql2"

Nothing Special. I tried changing that to mysql, or just "mysql2", it doesn't work. Errors that client is not initialized when I comment the whole line.

Netbeans stopped supporting rails. See :

Ruby Dropped in Netbeans 7,How to Use it in Netbeans7?

Did you get a message that your user is not allowed to install gems?

Then you should try following command in your rails application root folder

bundle install --path vendor/bundle

make sure to have the configurated database.yml in the config folder before running the previous command, or run it again after creating the file.
