Ruby Gem Twitter – 证书验证失败(Twitter :: Error :: ClientE

这是.rb代码：

require 'twitter'

puts "Greetings,World!"
puts "Checkpoint 1"
Twitter.configure do |config|
  config.consumer_key = "xxxxxxx" #removed for posting
  config.consumer_secret = "xxxxxxx" #removed for posting
  config.oauth_token = "xxxxxxx" #removed for posting
  config.oauth_token_secret = "xxxxxxx" #removed for posting
end
Twitter.verify_credentials
puts "Checkpoint 2"

我收到以下错误：

Greetings,World!

我是一个ruby新手,我无法理解客户端的错误……也许我错过了一些东西.我还确认我的Oauth凭据在python中工作.

在此先感谢,我期待着您的帮助.
