Hi all I’m running on my machine vindows vista home and ajust can not install ruby 1.8.7 or 1.9.1 on my machine. I used window-installer for this ruby release but after installing i can not install any gems like rails or wxruby . After tipping in cmd : gem install rails,it sais gem is not a internal or external command. What to do to make ruby to work?? ---

Just guessing here: you may have to manually put the command’s location in your PATH environment variable. Kind regards robert ---

Please see my previous comment about the lack of checking the box during installation. Even if you don’t added to the path, you can start a personalized command prompt from the application folder named “Command Prompt with Ruby 1.8.7” HTH, ---

I use Ubutu, but since I have been using windows before here are some tips. Goto command prompt type: ruby -v if you get something like this: ruby 1.8.7 (2010-01-10 patchlevel 249) [i486-linux] You have installed Ruby successfully. To install gem click this link: [http://rubyforge.org/frs/download.php/70697/rubygems-1.3.7.zip](http://rubyforge.org/frs/download.php/70697/rubygems-1.3.7.zip) , once you have downloaded it, extract it, navigate to the extracted directory with your command prompt and type ruby setup.rb I hope things will work fine.
