Hi I just installed ruby 1.8.6 stable version on windows xp pc. When I try to install gems by gem install gemname...it says 'command not recognized'. When I download a gem manually and put in the bin folder and then use gem install it will work. However, it is only working for some gems. Other error messages that I am getting is that the gem is of invalid format. Do you know why I can't run update gems outside of the bin folder or why some will not install?
