我正在尝试使用Faye-Websocket gem和EventMachine gem编写一个带websockets的简单ruby应用程序。
我正在开发OS X El Capitan 10.11.4
我使用自制软件安装了OpenSSL
/usr/local/Cellar/openssl
并成功将eventmachine安装到我的本地宝石中：
$ KG_CONFIG_PATH="$(brew --prefix openssl)/lib/pkgconfig" sudo gem install eventmachine
Building native extensions. This could take a while...
Successfully installed eventmachine-1.2.0.1
1 gem installed
我在我的应用程序中运行了一个成功的bundle install：
$ bundle install

Bundle complete! 3 Gemfile dependencies, 14 gems now installed.
但是，在尝试运行我的应用程序时，我仍然收到以下错误：
$ bundle exec ruby shield.rb
libc++abi.dylib: terminating with uncaught exception of type std::runtime_error: Encryption not available on this event-machine
Abort trap: 6
有关如何解决这个问题的想法吗？
