I had install ruby -version 2.2.4p230 but unable to install rails by using gem install rails. After writing this line in CMD the error saying Could not find a valid gem 'rails' (>= 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/latest_specs.4.8.gz)
I had searched a lot about this but didn't get anything useful for me. Please do a help for installing the rails.
