Answer 1

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/

Answer 2

Following fix solves the issue

   ==> cd /usr/local/Cellar/openssl/1.0.2s/lib/

==> sudo cp libssl.1.0.0.dylib libcrypto.1.0.0.dylib /usr/local/lib

Answer 3

For users of rbenv:

 brew uninstall openssl
 brew install rbenv/tap/openssl@1.0

 gem uninstall mysql2
 gem install mysql2 -v '0.4.10' -- --with-opt-dir="$(brew --prefix rbenv/tap/openssl@1.0)"

Answer 4

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.

Answer 5

Answer 6

In my case just uninstalling and installing the mysql2 gem did the trick

$ gem uninstall mysql2

$ bundle install
