gem eventmachine fatal error: 'openssl/ssl.h' file not found

Question

Just installed El Capitan and can\'t install gem eventmachine 1.0.7. openssl is at 1.0.2a-1. Tried to use --with-ss

Answer 1

I was trying to install v 1.0.3 and this worked for me.

gem install eventmachine -v '1.0.3' -- --with-cppflags=-I/usr/local/opt/openssl/include
