Hi,

I’m new to Ruby, RubyGems, RoR.

I successfully (so I believe) installed Ruby under my home dir. It’s  
in /home/dennis/installed/ruby-1.8.6

Now I’m trying to install rubygems-0.9.4. I’m following the  
instructions from [http://docs.rubygems.org/read/chapter/15#page101](http://docs.rubygems.org/read/chapter/15#page101)  
(Section 2.4: Installing gems in a non-standard directory.):

PREFIX=/home/dennis/installed/ruby-1.8.6  
export GEM\_HOME=$PREFIX/lib/ruby/gems/1.8  
export RUBYLIB=$PREFIX/lib/ruby:$PREFIX/lib/site\_ruby/1.8  
ruby setup.rb all --prefix=$PREFIX

This gives:

ruby: no such file to load – ubygems (LoadError)

_**Note the missing ‘r’ : “ubygems” instead of “rubygems”. This is not  
my typo - I copied this message literally from the command line.**_

Any help?  
thanks,  
–Dennis.

Hi Dennis,

What OS are you using? If linux have a look at  
[http://wiki.netbeans.org/wiki/view/RubyGems](http://wiki.netbeans.org/wiki/view/RubyGems)

Specifically the section “Installing your own private copy of Ruby on  
Ubuntu”

Cheers,

Anthony R.
