ruby-on-rails - 从命令提示符运行 Rails 应用程序时出错

Question

我在 Windows 8 中安装了 ruby​​ 版本为“ruby 2.1.5p273(2014-11-13 修订版 48405)[i386-mingw32]”的 rails 4.1.8。我按照本教程在 rails- 上安装了 ruby​​-“http://installfest.railsbridge.org/installfest/windows ”。现在，每当我运行任何 Rails 应用程序时，我都会收到此错误-

Fetching source index from https://rubygems.org/
Retrying source fetch due to error (2/3):Bundler::Fetcher::CertificateFailureError 
Could not verify the SSL certificate for https://rubygems.org/.
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'.

我要把 https 改成 http 吗？安全吗？

Answer 1

如错误信息所述:

For information about OpenSSL certificates, see bit.ly/ruby-ssl.

bit.ly/ruby-ssl 指向 http://railsapps.github.io/openssl-certificate-verify-failed.html其中有对正在发生的事情的解释，以及如何解决它的建议。

将 source 'http://rubygems.org' 中的 https 更改为 http 是推荐的解决方法之一。
