Bundler::Fetcher::CertificateFailureError: Could not verify the SSL certificate for https://rubygems.org/.
There is a chance you are experiencing a man-in-the-middle attack, but most likely your system doesn't have the CA certificates needed for verification. For information about OpenSSL certificates, see bit.ly/ssl-certs. To connect without using SSL, edit your Gemfile sources and change 'https' to 'http'.
An error occurred while installing rake (10.0.3), and Bundler cannot continue.
Make sure that `gem install rake -v '10.0.3'` succeeds before bundling.
我的 gemfile 包括gem "mysql2".
我是 OS X Lion，使用 Ruby 1.8.7。Rails 是 3.2.12。
我安装了 rake 顺便说一句。
