Hi guys, im trying an script that use Mongrel and Erubis, i just  
installed the gems with  
gem install mongrel  
gem install erubis

The installation went fine, without any error but everytime i try to  
run the script i get this message error,

`require’: no such file to load – erubis (LoadError)

It’s obvious that the script is not finding the previously installed  
gem, im using Ubuntu i installed rails using the .deb package in the  
repository and it works fine too, when i checked where was rails  
installed it is in the same path where rubygem installed the gems.

So i really don’t know where to check. Can somebody assist me with this.

Thanks

I think you likely are not telling Ruby that you are using gems.  
Either define the environment variable:

export RUBYOPT=-rubygems

(for bash, some shells do this differently)

in your shell, or add ‘-rubygems’ to the command line when starting  
ruby.

There might be other ways, but I don’t know them.

You can test this by running irb and trying to require erubis.

Cheers,

you can also just  
require ‘rubygems’
