I just built RHEL 6 and I need to be able to install ruby gems, etc. I have the ruby 1.8.7 packages installed but there is no gem command anywhere? What gives?
You probably have to install RubyGems. Try:
yum install rubygems
If it fails, try installing it by hand:
wget http://rubyforge.org/frs/download.php/74922/rubygems-1.8.4.tgz tar xzpvf rubygems-1.8.4.tgz cd rubygems-1.8.4 ruby setup.rb
Run the command below:
cp /usr/local/bin/gem /sbin
