bundle install fails with SSL certificate verifica

Question

When I run bundle install for my Rails 3 project on Centos 5.5 it fails with an error:

Gem::RemoteFetcher::FetchError: SSL_connect returned=1 errno=0 state=SSLv3 
read server certificate B: certificate verify failed 
(https://bb-m.rubygems.org/gems/multi_json-1.3.2.gem)
An error occured while installing multi_json (1.3.2), and Bundler cannot continue.
Make sure that `gem install multi_json -v '1.3.2'` succeeds before bundling.

When I try to install the gem manually (by gem install multi_json -v '1.3.2') it works. The same problem occurs with several other gems. I use RVM (1.12.3), ruby 1.9.2, bundler 1.1.3.

How to fix it?

Answer 1

The simplest solution:

rvm pkg install openssl
rvm reinstall all --force

Voila!

Answer 2

Thx to @Alexander.Iljushkin for:

gem update --system --source http://rubygems.org/

After that bundler still failed and the solution to that was:

gem install bundler

Answer 3

I was getting a similar error. Here is how I solved this: In your path directory, check for Gemfile. Edit the source in the gemfile to http instead of https and save it. This might install the bundler without the SSL certificate issue.l

Answer 4

To note, if you're grabbing gems from a source which SSL cert is trusted by an internal certificate authority (or you are connecting to an external source through a company web proxy with SSL inspection), point your SSL_CERT_FILE env variable to your certificate chain. This most likely just requires exporting your root certificate from your certificate store (System Keychain on macOS) to an accessible location from your shell i.e.:

export SSL_CERT_FILE=~/RootCert.pem

Answer 5

This issue should now be fixed. Update rubygems (gem update --system), make sure openssl is at the latest version on your OS, or try these tips of it's still not working: http://railsapps.github.com/openssl-certificate-verify-failed.html

Answer 6

I was just recently faced with this issue and followed the steps outlined here. There might be a chance that you are not pointing to the right OpenSSL certificate. After running:

rvm osx-ssl-certs status all
rvm osx-ssl-certs update all

and

export SSL_CERT_FILE=/etc/ssl/certs/ca-certificates.crt

the bundle complete ran!
