I have both 1.8.6 and 1.9.1 (both mingw under windows). My code requires windows-api, which requires win32-api. It works under 1.8. Under 1.9, I get : F:/Ruby19/lib/ruby/gems/1.9.1/gems/windows-api-0.4.0/lib/windows/api.rb:1:in `require': no such file to load -- win32-api (LoadError) from F:/Ruby19/lib/ruby/gems/1.9.1/gems/windows-api-0.4.0/lib/windows/api.rb:1:in`\’ The loaded gems are the same under 1.8 and 1.9 : The win32-api gem is the mswin32 one : win32-api-1.4.5-x86-mswin32-60. Any idea ? Thanks ! ---

Thanks ! 1. You’re using pre-compiled version of gems that are made to work on 1.8, not 1.9 Please install the DevKit for the MinGW version of Ruby and try install the gem again. ---

Additional note: OP should use: require ‘windows/api’ and not require ‘windows-api’ The latter causes error in both 1.8 and 1.9. bbiker ---
