Hi,
I'm getting a "Could not open any of [xml2, xslt, exslt] (LoadError)" error
when trying to run a simple Ruby program taken from the EXAMPLES.rdoc file of
the Mechanize gem.
The error is in this line of the Nokogiri module of libxml.rb: ffi_lib 'xml2',
'xslt', 'exslt'
Not sure if there are missing gems, and if so, what to install. Any ideas how
to fix this?
Thanks very much.
Gary M.
Program -- main.rb:
----------------------
## Google
require 'rubygems'
require 'mechanize'
a = WWW::Mechanize.new { |agent|
agent.user_agent_alias = 'Mac Safari'
}
a.get('http://google.com/') do |page|
search_result = page.form_with(:name => 'f') do |search|
search.q = 'Hello world'
end.submit
search_result.links.each do |link|
puts link.text
end
end
