require sqlite3 error in ruby upon starting server

Question

I am trying to install a ruby app on my local machine, I am trying to start the rails server command, but I get a long list of errors despite having installed the proper gems (or at least I think so)

I'm just copying the first few lines of my error here:

alex@alex-crunchbang:~/Documents/myapp$ rails server
=> Booting WEBrick
=> Rails 3.0.3 application starting in development on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server
Exiting

What could be the cause of my problem? Thanks everyone!

Run bundle install before starting Rails.
