Question

Update

Now that I've karma wh..err mined enough from this answer everyone should know that this should have been fixed.

re: via Ownatik again bundle install fails with SSL certificate verification error

gem update --system

My answer is still correct and left below for reference if that ends up not working for you.

Honestly the best temporary solution is to

[...] use the non-ssl version of rubygems in your gemfile as a temporary workaround.

via user Ownatik

what they mean is at the top of the Gemfile in your rails application directory change

source 'https://rubygems.org'

to

source 'http://rubygems.org'

note that the second version is http instead of https

Replace the ssl gem source with non-ssl as a temp solution:

• gem sources -r https://rubygems.org/
• gem sources -a http://rubygems.org/

The reason is old rubygems. You need to update system part using non ssl source first:

gem update --system --source http://rubygems.org/ (temporarily updating system part using non-ssl connection).

Now you're ready to use gem update.

If you're on a mac and use a recent version of RVM (~1.20), the following command worked for me.

rvm osx-ssl-certs update
