An error occurred while installing mysql2 (0.5.5), and Bundler cannot continue.
Make sure that `gem install mysql2 -v '0.5.5' --source 'https://rubygems.org/'` succeeds before bundling.
In Gemfile:
mysql2
already tryed installing libmysqlclient-dev, mysql-devel, and default-libmysqlclient-dev and the error persisted.
Also tryed looking the mkmf.log but couldnt get anything out of it. Mkmf.log:
