Error Installing Mysql2 on OSX

Attempting to install a specific version Mysql2 Gem. And I get this:

sudo gem install mysql2 -v '0.3.20'
Building native extensions.  This could take a while...
ERROR:  Error installing mysql2:
    ERROR: Failed to build gem native extension.

Don't know how to set rpath on your system, if MySQL libraries are not in path mysql2 may not load

Setting libpath to /usr/local/Cellar/mysql/5.7.16/lib

creating Makefile

make "DESTDIR=" clean

linking shared-object mysql2/mysql2.bundle
ld: library not found for -lssl
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [mysql2.bundle] Error 1

make failed, exit code 2

For reference I ran brew install mysql beforehand and it ran successfully. Also I tried uninstalling all versions of brew's mysql references just in case.

Is there something im missing? I've looked around and most pages point back to making sure you run brew install mysql which I have.

In case I wasn't more clear with my above explanation, the failure I am getting is after successfully running brew install mysql the error is from trying to install the gem afterwards via gem install mysql2 -v '0.3.20'

Any idea? Thanks

How to make it work on MacOS Mojave.

Make sure openssl is installed on Mac via Homebrew:

brew install openssl

Then install mysql2 gem following this special way:

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

where x.x.x - specified version of the mysql2 gem.

Just for reference what ended up working was xcode-select --install which seemed to install the OpenSSL libraries which took care of the ld: library not found for -lssl issue.
