syntax error on line 15, col 2: ` socket: /tmp/mysql.sock'

Hello World ( stackoverflow ) !

I started up my server, and I'm getting this :

Started GET "/demo/hello" for 127.0.0.1 at Tue Jan 18 16:42:42 -0500 2011

ArgumentError (syntax error on line 15, col 2: `  socket: /tmp/mysql.sock'):

My database.yml

socket: /tmp/mysql.sock

Those match.. so I checked my sockets in mysql..

    mysql> show variables like 'socket';
    +---------------+----------开发者_StackOverflow社区-------+
    | Variable_name | Value           |
    +---------------+-----------------+
    | socket        | /tmp/mysql.sock |
    +---------------+-----------------+
    1 row in set (0.00 sec)

So it's the right sockets...maybe its permissions?

mysql -u root -ppassword -h localhost my_database

Logs in, no problems.

I'm using the following:

mysql -v = 5.1.54 rails -v = 3.0.3 ruby -v = 1.8.7

Stumped! Any ideas what I may be missing?

This means there is a yaml syntax error. Usually it's a stray tab (make sure you don't have any tabs in that area of the yaml file -- delete all the whitespace and enter spaces just to be sure). If that's not the problem, it could be antoher syntax issue (if so, please paste your whole yaml file -- masking any sensitive information of course).
