Unable to install ruby-debug-ide on RubyMine 2.0: Windows with Ruby 1.8.7

Ok,

that's my workaround (that seems to work).

I have installed ruby 1.9 and the ruby-debug-ide19  (follow the manual) --- and it works.

Then I've changed back to 1.8.7 --- and ruby-debug-ide can be installed without an difficulty.

That' all folks

I have the same problem with Ruby 1.9.1 on Windows Vista x64. When I try to install ruby-debug-ide19, I get this error

Error running sassator: Failed to install gems. Following gems were not installed:

You need to install DevKit first. You may use instruction from http://giorgio-ferrara.blogspot.com/2009/11/how-to-enable-ruby-debug-in-rubymine-20_22.html

Worked for me, thanks.
