[José Fuentes]

Hello,

From this site : http://guides.rubyonrails.org/getting_started.html

Request: How can I continue with 3.1 installing rails, "gem install rails"

error:

C:\Sites>ruby -v ruby 2.2.4p230 (2015-12-16 revision 53155) [i386-mingw32] C:\Sites>gem install rails ERROR: Could not find a valid gem 'rails' (>= 0), here is why: Unable to download data from https://rubygems.org/ - SSL_connect retur ned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed ( https://api.rubygems.org/specs.4.8.gz) C:\Sites>
