我一直在尝试开发 Ruby on Rails 应用程序，但不能。我已卸载并重新安装，但它一直说找不到证书，即使我可以在我的计算机上看到证书。

C:\DevKit>gem install json --platform=ruby

    Unable to download data from https://rubygems.org/ - SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed (https://api.rubygems.org/specs.4.8.gz)
