I have installed ruby 1.9.2 on my centos server as per this tutorial - http://blog.jeffcosta.com/2010/09/10/7-steps-to-rails-on-centos/
It says that it should be installed to the following locations: /usr/local/include/ruby /usr/local/bin/ruby /usr/local/lib/ruby /usr/local/share/doc/ruby/html /usr/local/share/man1
However the only locations where there are things present are the 2nd and 3rd, the 2nd is the ruby installation (and is 1.9.2) the 3rd is a folder.
I have checked $PATH and /usr/local/bin is there
so I don't understand why I get this error '/usr/bin/ruby: No such file or directory' when I try to run 'ruby'
A bit of background, I uninstalled the yum version so I could install a newer version than 1.8.5 and therefore install gem and passenger.
