rest-client gem无法使用Clourflare Shared SSL，我收到以下错误：
irb(main):001:0> require 'rest-client'
=> true
irb(main):002:0> RestClient.get('https://bkam.com')
RestClient::SSLCertificateNotVerified: SSL_connect returned=1 errno=0 state=error: certificate verify failed:

以下是我用cURL尝试相同的网址时
#curl -I https://bkam.com

但是，当我尝试使用与Google.com或CloudFlare.com相同的方法时，它运行正常！
我在OS X Yosemite（10.10.3）上运行OpenSSL 1.0.2c 2015年6月12日，ruby 2.2.2p95和rest-client 1.8.0
