gem install sass error

I am trying to install sass and I tried ruby installer. I am getting the error as follow.Please anyone help.
C:\Ruby23-x64>gem install sass
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.org/specs.4.8.gz)
gem install by default uses https://rubygems.org/ as it's source for gems, but you can specify the source using --source option and give a non-SSL source to install like following:
gem install sass --source http://rubygems.org/

ruby gem on windows 10 not working

I am trying to install sass with ruby on my windows machine gem install sass but it is not working.
I get the following error:
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)
After googling around I found this workaround:
https://gist.github.com/luislavena/f064211759ee0f806c88
The thing is that I already have an AddTrustExternalCARoot-2048.pem in my ssl_certs directory.
gem --version shows 2.4.5.1
I am using windows 10 and downloaded the installer from ruby website: http://rubyinstaller.org/downloads/
ruby -v shows ruby 2.2.5p319 (2016-04-26 revision 54774) [i386-mingw32]
What can I do?
You can go into your gemfile and change the source to http://rubygems.org (lose the https://).

Cannot install cucumber

I have installed Ruby by way of the command prompt. Verified that I had the most updated version. I am now trying to install cucumber. Right on the cucumber site, it says to simply use the prompt gem install cucumber to get it to install. Gem fails to make the call to cucumber with these result on the command prompt:
ERROR: Could not find a valid gem 'cucumber' (>= 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)

Ruby DevKit Unable to Download Date from Rubygens.org

I've installed the ruby devkit on Windows 7 but it's unable to install json using the following command:
gem install json --platform=ruby
I'm getting this error:
ERROR: Could not find a valid gem 'json' (>= 0), here is why:
Unable to download data from https://rubygems.org/ - SSL_connect returned=1 errno=0 state=SSLv2/v3 read server hello A:
unknown protocol (https://api.rubygems.org/specs.4.8.gz)
I'm on ruby 2.3.1p112 with RubyGems 2.5.1.
If you have a Gemfile, change the first line in Gemfile from https to http, it should do the trick.
Also, you can install gems global by creating a Gemfile and running bundle install from the directory the Gemfile is created. So, instead of using the gem install command, create a Gemfile and run bundle install in it.
This is the original
source 'https://rubygems.org'
gem 'test'
Change to
source 'http://rubygems.org'
gem 'test'
If you don't, you can pass the -s option to gem install and specify the url to http://rubygems.org

Thanks for any help you can provide.
You could try to just get it from http://rubygems.org/
If you want to use Rails on windows, I suggest you to look at this installer which is pretty great : RailsInstaller
