Cannot load such file -- ffi_c error in RubyMine

I tried to run a simple script as follows to learn automation using watir-webdriver and Ruby. But I am getting no such class error -ffi_c. 

class TestWatir
  require 'watir-webdriver'
  require 'cucumber'
  browser = Watir :: Browser.new :firefox
  browser.goto 'http://www.google.com'
end

I've added Cucumber and Watir-webdriver gems and also checked there is ffi dependency in the external library.

Solution

  • I had this problem and resolved it by:

    del Gemfile.lock
bundle clean --force
gem install bundler -v 1.12.1
gem install ffi -v 1.9.10 --platform=ruby
bundle install

    It seams that some versions of ffi era labeled with the incorrect platform or something like that, that's bringing some problems on windows.

    Hope it helps!
