从命令提示符运行rails应用程序时出错

Question

我有rails 4.1.8的红宝石版本“ruby2.1.5p273 (2014-11-13修订版48405) i 386-mingw32”在windows 8中。我遵循本教程安装rails“http://installfest.railsbridge.org/installfest/windows”。不管我什么时候运行rails应用程序，我都会收到这个错误-

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

正如错误消息所述：

有关OpenSSL证书的信息，请参见bit.ly/ruby。

Bit.ly/ruby指向http://railsapps.github.io/openssl-certificate-verify-failed.html，它解释了正在发生的事情，并就如何修复它提出了建议。

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

底部有一个windows特定的解决方案，建议下载一个用于cacert.pem的RailsInstaller。

Answer 2

这可以通过运行gem update --system来解决。

不久之前，我自己也遇到了同样的问题，这为我解决了这个问题。

Answer 3

只需转到根目录中的gem文件，并将"https“替换为"http”在最上面的行中。
