SeleniumRubyWindowsTest.rb:1:in `require': no such file to load -- selenium (Loa dError) from SeleniumRubyWindowsTest.rb:1

I followed the steps from this blog - http://testnerdy.blogspot.ca/2009/10/installing-ruby-and-selenium-on-windows.html

This blog is a little dated, so I am assuming it has to do with that. Anyone have any ideas on what I may be doing wrong?

Code as requested (this is copy/pasted from http://testnerdy.blogspot.ca/2009/10/running-selenium-tests-written-in-ruby.html)

require "selenium"
require "test/unit"

class SeleniumRubyWindowsTest < Test::Unit::TestCase
  def setup
    @verification_errors = []
    if $selenium
      @selenium = $selenium
      @selenium = Selenium::SeleniumDriver.new("localhost", 4444, "*chrome", "http://www.yahoo.com/", 10000);

  def teardown
    @selenium.stop unless $selenium
    assert_equal [], @verification_errors

  def test_SeleniumRubyWindowsTest
    @selenium.open "/"
    assert_equal "Yahoo!", @selenium.get_title
    @selenium.type "p_13838465-p", "Selenium RC"
    @selenium.click "search-submit"
    @selenium.wait_for_page_to_load "30000"
    assert_equal "Selenium RC - Yahoo! Search Results", @selenium.get_title
  • what file are you referencing at line 1 ? Is it there ? Can you include your code ? Aug 8, 2012 at 15:15
  • what happens if you open up irb and type "require 'selenium' " ? Aug 8, 2012 at 20:34
  • irb(main):001:0> require "selenium" LoadError: cannot load such file -- selenium from C:/RailsInstaller/Ruby1.9.3/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in require' from C:/RailsInstaller/Ruby1.9.3/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in require' from (irb):1 from C:/RailsInstaller/Ruby1.9.3/bin/irb:12:in `<main>' does this mean I have a bad install?

  • seems so - what happens if you do 'gem uninstall Selenium' ? Aug 8, 2012 at 23:48
  • if that works, do 'gem install Selenium' Aug 8, 2012 at 23:49

1 Answer 1


Seems my suggestion of doing a gem uninstall and then an install worked
