Ubuntu 11.04 + RubyDebug

Ruby
1

I have a fresh Ubuntu 11.04 install and have installed Ruby full (sudo
apt-get install ruby1.9.1-full). I have also installed Ruby Gems 1.8.5,
and RubyMine.

I cannot get gem RubyDebug (and several other gems) to install from
cmd-line

  • it complains that linecache19 requires Ruby 1.9.2. I have also
    installed rvm because googling around showed some people with same
    problem was able to solve using rvm - but not working for me.

I have added some commands and results below.

Any ideas how to get this working? I’m willing to wipe the drive and
start fresh if needed.

Thanks,

Since you’ve installed 1.9.2 under rvm, what if you do

rvm use 1.9.2

before doing the gem install?

I had tried that earlier, but I tried again with same result See below.

I appreciate your help. All ideas are welcome!
