I've tried many solutions but nothing seems to work! I use Ruby 1.9.3 and Rails 3.1.3 and I want to install the ruby-debug19 gem. This ist what I get from the PowerShell:
PS C:\Users\**\**\**> gem install ruby-debug19

I've had a similar issue getting ruby-debug-base19x installed and I've been able to get it successfully installed using the following:
gem install ruby-debug-base19x -v 0.11.30.pre3
This worked on my development machine which is running window 7 along with pik (see https://github.com/vertiginous/pik), devkit (see https://github.com/oneclick/rubyinstaller/wiki/development-kit) and Ruby 1.9.3p0 / 1.9.2p290
Here's a sample of what you should see when installing it:

While this worked for me it is a moving target in that we're using a pre release version of the gem to get things done. Best to keep a eye out for a release.
Just an additional note that at the time of writing the current pre release was 0.11.30.pre6 which doesn't work so just doing the following will fail:
gem install ruby-debug-base19x --pre
