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

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

pristine removes the old gem and recompiles it.

The cpp flags option allows the compiler to find the openssl headers.

You can also add the version if you like:

gem pristine eventmachine -v '1.0.4' -- --with-cppflags=-I/usr/local/opt/openssl/include
