Why have Rails & Bundler package have dissapeared?

Question

I'm following Michael Hartl's Ruby on Rails tutorial & everything has been working fine until I reached this stage.

For some reason when I try to run a bundler or the rails command it says they are not installed even though they were working before & I've tried to reinstall them.

Could this have something to do with my rvm gemset? I'm not sure how to check the rvmrc file.

Or could it be something to do with my OS. I'm working on ubuntu 12.10 on a virtual box hosted in windows 7.

Thanks in advance for your help.

If it helps here is the repo for the app.

This issue was caused by a amendment I made to my ~/.bashrc file to customize the prompt in my terminal. I had put PS1='\[\033[01;31m\]\W: \[\033[01;33m\]\$ \[\033[01;37m\]' at the bottom of the ~/.bashrc file.

I had to remove PS1='\[\033[01;31m\]\W: \[\033[01;33m\]\$ \[\033[01;37m\]' & completely uninstall & remove RVM & Ruby from my system & reinstall them. I tried rvm implode to remove everything but this didn't work at first, it said rvm was not installed! When I tried source ~/.rvm/scripts/rvm, I was able to succesffully run rvm implode.

I was able to customize my prompt by putting:

PS1='\[\033[01;31m\]\W: \[\033[01;33m\]\$ \[\033[01;37m\]'

source ~/.rvm/scripts/rvm

into my ~/.bash_profile

It looks like you missed last step of rvm install section of the tutorial:

$ rvm use 1.9.3@rails3tutorial2ndEd --create --default
Using /Users/mhartl/.rvm/gems/ruby-1.9.3 with gemset rails3tutorial2ndEd
