Error installing Bundler

Question

I am trying to install the Bundler gem on my Mac. With the command: sudo gem install bundler I get the following error:

ERROR:  Could not find a valid gem 'bundler' (>= 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://s3.amazonaws.com/production.s3.rubygems.org/latest_specs.4.8.gz) 

It clearly seems to be a server issue, but how do I go about solving this? gem update --system is currently up-to-date. Is there an alternative way to get Bundler?

Had the same issue and everything is described here: http://railsapps.github.io/openssl-certificate-verify-failed.html

tl;dr Recent versions of RVM, the Ruby Version Manager, include a utility to diagnose and resolve errors caused by outdated certificate files. See the article Installing Rails for instructions and advice. The RVM website explains how to install RVM.

If you’ve installed RVM, try this:

$ rvm -v # rvm 1.19.1 (stable) $ rvm osx-ssl-certs status all # Certificates for... $ rvm osx-ssl-certs update all # Updating certificates... 

That’s all that is needed to resolve the issue if you are using RVM (you must be using RVM version 1.19.1 or newer).

Windows users:

You can't run rvm command on Windows as you can see here, but you can fix the error without it. Just add a new source adress with http instead of https:

gem sources -a http://rubygems.org 

Then you can run:

gem install bundler
