我收到以下错误

C:/Ruby193/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require': 126: The specified module could not be found.   - C:/Ruby193/lib/ruby/gems/1.9.1/gems/mysql2-0.3.11-x86-mingw32/lib/mysql2/1.9/mysql2.so (LoadError)

尝试运行此脚本时…

require "mysql2"

client = Mysql2::Client.new(:host => "localhost", :username => "root", :password => "system32")
results = client.query("SELECT * FROM project1_nodes").each do |row|
  puts row
end

有任何想法吗？
