Getting the following error after running rake db:migrate

rake aborted!
LoadError: dlopen(/Users/scott/.rbenv/versions/2.4.1/lib/ruby/gems/2.4.0/gems/mysql2-0.4.10/lib/mysql2/mysql2.bundle, 9): Library not loaded: libssl.1.0.0.dylib

What does the libssl refer to?

So the answer to my own question was the following - out of the 5 or so other solutions on stackoverflow, this is the only one that worked:

brew install openssl

cd /usr/local/Cellar/openssl/1.0.1f/lib

sudo cp libssl.1.0.0.dylib libcrypto.1.0.0.dylib /usr/lib/

First uninstall the mysql2 gem:

gem uninstall mysql2

Make sure you installed openssl:

brew install openssl

It will print out some notes. We are interested in this part:

For compilers to find this software you may need to set:
LDFLAGS:  -L/usr/local/opt/openssl/lib
CPPFLAGS: -I/usr/local/opt/openssl/include

Then you can re-install mysql2 gem like this:

gem install mysql2 -v 0.4.10 -- --with-cppflags=-I/usr/local/opt/openssl/include --with-ldflags=-L/usr/local/opt/openssl/lib

You should be good to go.
