How to fix an error when downloading gem packages?

Question

Ruby on Rails

I have win8, installed Ruby on rails, started installing sass with gem install sass and got this error:

ERROR:  Could not find a valid gem 'sass' (>= 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.o
rg/latest_specs.4.8.gz)

The same error pops up on any connection through the gem.
I searched the Internet, but what I found did not solve this problem.
Unfortunately, I'm not strong in Ruby to figure it out myself :(
How to fix this error?
