Has anyone seen an error like this before? I have the command line tools - never ran into an error compiling this gem on my old laptop also running Yosemite.

First set the path of the brew openssl executable in your shell. (zshrc or bashrc). Source your shell.

Then do

 which openssl

Get the output and use it in your gem install dir path.

gem install eventmachine  -v '1.2.7' -- --with-openssl-dir=/usr/local/opt/[email protected]/bin/openssl

This worked for me.

I understand this question has been asked quite a while ago but I've seen this error just now and after trying all answers and struggling with this and another couple of gems I've realized that as I was trying to install a pretty old project and therefore some gems were not compatible with current libs and most of them were actually requirements for the actual project gems.

What I did then was remove the Gemfile.lock file and let bundler recreate it with more current references for the dependency gems and that worked for my case and therefore I'm contributing to others that eventually get on the same situation:

rm Gemfile.lock
bundle install

Hope that helps!

Try this

gem install eventmachine -- --with-cppflags=-I/usr/local/opt/openssl/include

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. :)

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

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

In case the above answer doesn't help you, you can try downgrading your Ruby version to 2.1.2. That did the trick for me (OS 10.10.2). Add this at the top of your Gemfile:

ruby '2.1.2'

I remember installing another gem that required eventmachine and it gave me problems in windows. I had to install DevKit tools and that resolved my issue. sorry i cannot provide more details but I hope it helps to solve your issue. you can also try what Prakash shared above. I had to update myself in the end after installing Devkit.
