Ruby on rails “错误”；无法验证的SSL证书https://code.stripe.com/"

我在尝试安装stripe时收到以下错误消息。这个问题有解决办法吗？ 我正在学习关于条纹的教程

"Fetching source index from https://code.stripe.com/
 Fetching gem metadata from https://rubygems.org/.........
 Could not verify the SSL certificate for https://code.stripe.com/.
 There is a chance you are experiencing a man-in-the-middle attack, but most
 likely your system doesn't have the CA certificates needed for verification. For
 information about OpenSSL certificates, see bit.ly/ruby-ssl. To connect without
 using SSL, edit your Gemfile sources and change 'https' to 'http'."

这在具有过时证书包的旧系统上很常见。更新证书捆绑包将解决此问题。有关如何执行此操作的说明，请访问邮件中的链接。的可能重复项
