I've got two MacBooks (one on Mavericks, the other on Yosemite) and the same thing happens on both. After installing Ruby 2.2.3 with RVM, I get the following error:
.rvm/rubies/ruby-2.2.3/lib/ruby/2.2.0/net/http.rb:923:in `connect': SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed (Faraday::SSLError)
I've tried searching for a solution online, but nothing seems to work. Most of the people having this issues are running Windows machines.
$ rvm osx-ssl-certs status all
Certificates for /usr/local/etc/openssl/cert.pem: Up to date.
Certificates for /etc/openssl/cert.pem: Up to date.
Switching back to 2.2.2 works fine. Any thoughts?
Downloading http://curl.haxx.se/ca/cacert.pem and adding
export SSL_CERT_FILE=PATH_TO_THe_DOWNLOADED_FILE/cacert.pem
to the .bash_profile/.zshrc partially fixed the issue, because it throws the following error on my system:
Excon::Errors::SocketError: Unable to verify certificate, please set `Excon.defaults[:ssl_ca_path] = path_to_certs`, `ENV['SSL_CERT_DIR'] = path_to_certs`, `Excon.defaults[:ssl_ca_file] = path_to_file`, `ENV['SSL_CERT_FILE'] = path_to_file`, `Excon.defaults[:ssl_verify_callback] = callback` (see OpenSSL::SSL::SSLContext#verify_callback), or `Excon.defaults[:ssl_verify_peer] = false` (less secure).
Setting Excon.defaults[:ssl_verify_peer] to false in a Rails initializer (only on development/test envs) makes it work.
Update: Reinstalling 2.2.3 from source got rid of all my problems.
rvm remove 2.2.3
rvm install 2.2.3 --disable-binary
Couldn't help myself otherwise than with brew install openssl on El Capitan. I've tried everything like updating certs using RVM, replacing SSL certs from haxx.se, or reinstalling ruby. Nothing else worked.
