Error installing EventMachine gem on OSX Yosemite

ruby-on-rails ruby gcc osx-yosemite eventmachine

EventMachine 1.0.3 didn’t work with Ruby 2.2. This was fixed in EventMachine 1.0.4. You can most likely fix your situation by upgrading EventMachine with

bundle update eventmachine

ruby-on-rails ruby gcc osx-yosemite eventmachine

For El Captain, this worked for me:

$ bundle update eventmachine # updated to v1.0.8$ bundle config build.eventmachine --with-cppflags=-I/usr/local/opt/openssl/include$ bundle install

ruby-on-rails ruby gcc osx-yosemite eventmachine

if you have brew install, try

brew install openssl

and if it still says,

Warning: openssl-1.0.2e already installed

then run this command ,

brew link openssl --force

it will do the trick. :)
