I am new to working with Ruby on Rails. I am attempting to run the rails server command and keep coming up with this error:

Do you have the MySQL client libraries installed? Library not loaded: libmysqlclient.18.dylib indicates that you don't or they can't be found. — mu is too short

Have you tried switching your application over to SQLite to see if that works without issue? Have you uninstalled and then reinstalled the MySQL packages? — Schleichermann

Silly question but: you have installed the mysql gem, but have you actually installed the mysql application yet?

The mysql gem is just some code that talks to the existing application that you must install on your system.
