I get "Certificate Verify Failed" on installing Bundler for Ruby on Rails, on Windows 7. Ruby 1.9.3

Question

I've tried everything what I understood in my short knowladge of Programming.

When I enter "bundler install" I get "Certificate Verify Failed" (I've checked the certificate, it's updated) Then it ends up with "Make sure "gem install [gem's name] -v [version] succeds before bundling."

So I decided to install Gem-per-Gem, instead of trying to solve they certificate issue.

Will this work or I'm just wasting my time?

I am having a similar issue when attempting to update or install anything gem related...not certain how this all works and I'm trying to find a better understanding of what's going on as well...will keep this stream posted with anything that works for me – Flex

Found it!

Most importantly...download https://raw.githubusercontent.com/rubygems/rubygems/master/lib/rubygems/ssl_certs/AddTrustExternalCARoot-2048.pem

Figure out where to stick it

C:\>gem which rubygems
C:/Ruby21/lib/ruby/2.1.0/rubygems.rb

Then just copy the .pem file in ../2.1.0/rubygems/ssl_certs/ and go on about your business.

NOTE The above link is currently down as of 10/12/2016. Commentary led me to do some follow-up research and it appears to be a continuing problem and is not being directly discussed. There are other topics directly on the rubygems KB you may want to follow --> http://help.rubygems.org/search?utf8=%E2%9C%93&q=SSL+Certs&t=d&scope=all&category_id=&recommend=1

Some browsers (e.g. Chrome) may save the .pem file as .txt, be sure to change this back to just .pem. – Monge

The download link doesn't work anymore. Is there any alternate download link? – Soutache

Try updating to the latest bundler gem. The new certs are bundled starting with version 1.12.0. – Flex

The .pem file listed here (and on the gitub gist link in this answer) is now a 404. Suggestions? – Alltime

The certificate is here now: raw.githubusercontent.com/bundler/bundler/master/lib/bundler/… – Electro

Try replacing 'https://rubygems.org' with http://rubygems.org in the GemFile
