rubygems setup.rb: no such file of directory

I have a small question. When I tried to install rubygems b开发者_运维问答y following the code here:

wget 'http://rubyforge.org/frs/download.php/60718/rubygems-1.3.5.tgz'

tar -vxzf rubygems-1.3.5.tgz

cd rubygems-1.3.5

ruby setup.rb

But when I try to do ruby setup.rb it says bash: /usr/bin/ruby: No such file or directory . So I tried which ruby and it says /usr/local/bin/ruby

Any ideas how I can fix this path thing?

i got this to work,i had to update my path on /root and /home for this to work.

vim .bash_profile in root and home replace PATH with PATH=$PATH:$HOME/bin:/sbin:/usr/bin:/usr/local/bin

and it's working now
