trouble reinstalling ruby

I had to uninstall then reinstall ruby. When I went to install it the installation went off without a hitch except for a strange error:

ERROR: Error running 'bunzip2 '/home/tom/.rvm/archives/ruby-1.9.2-p180.开发者_JAVA技巧tar.bz2'', please read /home/tom/.rvm/log/ruby-1.9.2-p180/extract.log

Now when I go to install rails it alerts me that I'm...

Missing RVM environment file: '/home/tom/.rvm/environments/ruby-1.9.2-p180@rails3tutorial'

I need to uninstall ruby, install zlib via rvm install package zlib, then install ruby 1.9.2.

Can anyone give me a walk through. I'm completely new and utterly confused. I've searched the web but can't find a walk through that works.

run rm -rf /home/tom/.rvm/ That will delete RVM and all installed packages. Reinstall RVM using the instructions from this page https://rvm.io
