Question

I am having a problem installing the mysql2 gem.

This comes up when I do gem install mysql2:

Marks-MacBook-Pro:~ Mark$ gem install mysql         


        

Answer 1

This command worked for me:

gem install mysql2 -- --srcdir=/usr/local/mysql/include

Answer 2

Make sure openssl is installed on Mac via Homebrew.

brew install openssl

Install mysql2 gem.

gem install mysql2 -v '0.5.2' -- --with-ldflags=-L/usr/local/opt/openssl/lib --with-cppflags=-I/usr/local/opt/openssl/i

Answer 3

The following worked for me

brew install mysql 
brew install mysql-connector-c
gem install mysql2

Answer 4

It seems that it cannot find the MySQL library. Have you installed MySQL?
Try installing it via homebrew:

brew install mysql

or install it via macports or fink or whatever you prefer.

Then try again with:

gem install mysql2

Answer 5

I don't need MySQL on Mac OS X, because I have MySQL installed on Vagrant box. Therefore, I just installed mysql-connector-c.

brew install mysql-connector-c
gem install mysql2

Answer 6

You'll have to specify some additional environment variables to install this gem on the 64 bit architecture for Mac OSX 10.6:

env ARCHFLAGS="-arch x86_64" gem install mysql2

If you are using rvm you can add this as your default option in the ~/.rvmrc file:

rvm_archflags="-arch x86_64"
