Error installing mysql2: Failed to build gem native extension

Question

I am having some problems when trying to install mysql2 gem for Rails. When I try to install it by running bundle install or gem install mysq

Answer 1

Solution only works on Mac OS X

If you've installed MySQL with homebrew, what worked for me was uninstalling MySQL, and installing MySQL Community Edition via the MySQL website (https://www.mysql.com/).

After installed, just re-enter the command to gem install mysql2 or if necessary, sudo gem install mysql2, if you are getting permission denied problems.
