“无法从https://rubygems.org/下载数据”，因为“证书验证失败”

Question

I added this code to my mydbs_controller.rb as instructed on the Rails tutorial:

def create
  @mydbs = Mydb.new(params[:mydb])

  @mydb.save
  redirect_to @mydb
end

I run my database and come up with this error:

 The controller-level `respond_to' feature has been extracted to the `responders` gem. Add it to your Gemfile to continue using this feature: gem 'responders', '~> 2.0' Consult the Rails upgrade guide for details. 

So I added gem 'responders', '~> 2.0' to my gemfile and tried a bundle install.

I run into another error telling me

Make sure that gem install responders -v '2.1.0' succeeds before bundling.

After running that I'm left with yet another error

ERROR: Could not find a valid gem 'responders' (= 2.1.0), here is why: 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)

Answer 1

I meet same question. Then I change the gem source from " https://rubygems.org/ " to " http://rubygems.org/ "

Answer 2

So my problem was that i needed to be running on ruby version 2.2.2. However that update (only for windows users) pulled a lot of errors that I found to not appear on the mac.
