I've installed xampp, made a mysql database, installed Ruby on Rails, made a site, and when I tried installing mysql2, with "gem install mysql2" on guibash, I get this error:
$ ––gem install mysql2
ERROR: Error installing mysql2:

-------------------------------
Now for the sake of not repeating this wall of text, let's call that error A. I've tried also tried gem install mysql2 --platform=ruby (error A).
Now the only way I've been able to install mysql is by downloading the the lib and using : gem install mysql2 -- '--with-mysql-dir=C:\MySQLConn' with MySQLConn including the library, and that does it.
$ gem list mysql2
mysql2 (0.5.4)
But whenever I use "Rails server" I get:

What can I try to resolve this?
