Answer 1

what rails do you use??

I think your problem is the version of rails.

I use:

gem 'rails', '4.1.4'
gem 'sass-rails', '~> 4.0.3'

Some times https://rubygems.org is the problem I need to change for http://rubygems.org, I think the problems is for proxy.

Try disabling Ipv6 on your system. If on Linux you can use these commands.

 sudo sysctl -w net.ipv6.conf.all.disable_ipv6=1
sudo sysctl -w net.ipv6.conf.default.disable_ipv6=1

TL;DR Apply the official fix:

1. Download https://rubygems.org/downloads/rubygems-update-2.6.7.gem

2. Run:

   gem install --local rubygems-update-2.6.7.gem
   update_rubygems --no-ri --no-rdoc
   gem uninstall rubygems-update -x
   

Long version

See http://guides.rubygems.org/ssl-certificate-update/ .

Basically it adds GlobalSignRootCA. Very easy to apply, unfortunately hard to google though.

I also noticed issues with rubygems.org yesterday (in one environment), but your error almost sounds like an issue with a newly-installed Ruby and its SSL integration/configuration (having it locate SSL during installation, as well as the necessary certificates).

You might check out:

SSL Error When installing rubygems, Unable to pull data from 'https://rubygems.org/

But if that doesn't help I recommend continued searching, as this seems to be a common problem area.

Answer 5

According to this post : SSL Error When installing rubygems, Unable to pull data from 'https://rubygems.org/

Goto link http://rubygems.org/pages/download

Download the latest zip file
Unzip it
run "ruby setup.rb" in unzipped folder
now run gem install command
