One of my previous students, Ross Kinney recently blogged about an error he encountered:
Gem::RemoteFetcher::FetchError: SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed (https://s3.amazonaws.com/production.s3.rubygems.org/gems/multi_json-1.7.7.gem)
It turns out that some of the OS X SSL Certs were out of date and he fixed it by running:
rvm osx-ssl-certs update all
I had initially filed that away under “Good to know”, but after this weekend and yesterday, I’ve used this solution a half dozen or more times. Thanks Ross Kinney!
