Hi Everyone, I have updated to rails 3. When I try to run my rails server by doing this command: "rails server". I get this error: "Could not find linecache-0.43 in any of the sources. Try running ''bundle install''. I try bundle install and I get another error saying installing linechaceh <0.43> with native extensions C:/Ruby192/lib/ ruby/1.9.1/rubygems/installer.rb:483:in ''rescue in block in build_extensions'': ERROR: Failed to build gem native extension. <Gem::Installer::ExtensionBuildError> C:/Ruby192/bin/ruby.exe extconf.rb can''t handle 1.9.x yet ***extconf.rb failed*** Could not create Makefile due to some reason, probably lack of neccessary libraries and/or headers.
