Newbie question 'require'

ruby-talk
1

Hi I've installed the sqlite3-ruby gem via gem install. However when I do a:

require 'sqlite3'

I get a LoadError: no such file to load — sqlite3. This is on Mac OSX 10.5.2. Yes I have slite3 installed and working. I checked the gems directory and the sqlite3.rb file exists. I'm obviously missing something obvious.

Any pointers would be appreciated.

Try adding
require 'rubygems'

When you install a gem you must use RubyGems to load it as well. Did you enable RubyGems in your pgm before reequiring sqlite3? The simplest (tho' least robust) way is to add

require 'rubygems'

at the top of your program.

You could also add,

export RUBYOPT=rubygems

to your .profile file. This is the solution I use as I avoid having to
type require 'rubygems'

on every script that has a gem lib file as a dependency.

If you don't know how to set environment variables in BASH, google would
be a good start.

You're welcome! I had the problem a few month ago, when I installed
Ruby on Windows without admin rights. Had to include that, because the
RUBYOPT enviroment variable didn't exist. Write -rubygems in it and
you don't have to require them every time.

Have fun with Ruby!
