Hi, VERY new to Ruby…talk to me like I’m 6 years old 🙂 I’m tryin to install a debugger. Downloaded Ruby-Debug-0.10.1.gem When I type GEM INSTALL RUBY-DEBUG I get : A Socket operation attempted to an unreachable host Not using rails…all I’ve done is install Ruby-one-click into an XP laptop. ---

Alright…no response. I must have left out some info, or I typed an undecipherable question…lemme rephrase: I need a debugger for Ruby. Any suggestions where to get one & how to load it? ---

Any suggestions where to get one & how to > load it? That is a network error of some sort - I get a similar one due to my office firewall. But if you have already downloaded Ruby-Debug-0.10.1.gem onto your harddrive, then all you need to do is change to the download directory and type `gem install -l Ruby-Debug-0.10.1.gem` The -l for local makes it skip the attempt to connect to the network. If you haven’t downloaded it, you can get it from [rubyforge.org/projects/ruby-debug/](http://rubyforge.org/projects/ruby-debug/) -Adam ---

ERROR: While executing gem … OptonParser::InvalidOption invalid option: -1 I’m on Ruby ver 1.8 (I think???) I ran that from the download dir where Ruby-Debug-0.10.1.gem and 3 other files that came along w/ the download are. ---
