Problem launching WEBrick in Rails

Rails
1

Hey everyone, i’m super new to Rails and excited to get going! I’m
following the Ruby on Rails Essentials 3 tutorial from Lynda very
closely and came across an error at the step when launching WEBrick.

MY Setup:
I am on OS X. I have installed the MySQL client and ran it from my OS
X system prefs. I double checked my gems and mysql (2.8.1) and mysql2
(0.3.6, 0.2.11) are BOTH listed in my local gems list in terminal. I
can launch MySQL in terminal as well.

Problem:
So, the issue is that when launching WEBrick via the ‘davidd$ rails
server’ command I get:

davidd$ rails server
/Library/Ruby/Gems/1.8/gems/mysql2-0.2.11/lib/mysql2/mysql2.bundle:

Any cause for this? Is there any way I can remove the mysql gems and
try re-installing them? Thanks so much for any help you guys may have!

Hopefully you may have solved the issue by now, if not, this is what you
can
do on your mac

On Mac OS X:

sudo gem install mysql – --with-mysql-dir=/usr/local/mysql

On Mac OS X Leopard:

sudo env ARCHFLAGS="-arch i386" gem install mysql –

–with-mysql-config=/usr/local/mysql/bin/mysql_config

This sets the ARCHFLAGS environment variable to your native

architecture

This is from the config/database.yml file

To uninstalling previous version of gem may not be required, but you can
uninstall it using:
sudo gem uninstall mysql

Create a soft link by command -
sudo ln -s /usr/local/mysql/lib/libmysqlclient.18.dylib
/usr/lib/libmysqlclient.18.dylib
