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

One alternative is to add a bundler config entry for your whole user profile, like this:

cd ~
bundle config build.eventmachine --with-cppflags=-I$(brew --prefix openssl)/include

it'll create a .bundle/config file in your home directory, which is then used in all your projects when you run bundle install.
