Issue to start the Rails built-in server

Question

When I hit the command to star the Rails server I always get this message:

I'm using the mysql2 gem and I'm trying to use mysql from WampServer.

Thanks for your help.

I guess you are looking for the following:

Ruby mysql2 Error

After installing the gem do the following:

Install the mysql2 gem with paths pointing to where you installed the MySQL Connector library and includes.

NOTE: Make sure you do have the single quote (') as shown below:

gem install mysql2 -- '--with-mysql-lib="C:...\\MySQL Connector C 6.0.2\\lib\\opt" --with-mysql-include="C:...\\MySQL Connector C 6.0.2\\include"'
