Hello everyone. I am new to Rails (and Ruby) and when I was going  
through the example in chapter 4 of Agile Web D. on Rails, I  
ran into a problem.

I think the issue is where rails is looking for sqlite3. Any help would  
be appreciated.

Thank you!

Here is the versions and locations of sqlite3 and rails:

dyn-129-64-208-106:tst yegeniy$ sqlite3  
SQLite version 3.4.0  
Enter “.help” for instructions  
sqlite\> dyn-129-64-208-106:tst yegeniy$  
dyn-129-64-208-106:tst yegeniy$ which sqlite3  
/usr/bin/sqlite3  
dyn-129-64-208-106:tst yegeniy$ which rails  
/usr/local/bin/rails  
dyn-129-64-208-106:tst yegeniy$ echo $PATH$  
/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:/opt/local/bin:/usr/local/git/bin:/usr/texbin$

This is the output of running script/server in the tst folder (created  
with ‘rails tst’ command:

dyn-129-64-208-106:tst yegeniy$ script/server

with lots more of similar messages.

Also, this is my config/database.yml file:

dyn-129-64-208-106:tst yegeniy$ vi config/database.yml

# SQLite version 3.x

# gem install sqlite3-ruby (not necessary on OS X Leopard)

development:  
adapter: sqlite3  
database: db/development.sqlite3  
pool: 5  
timeout: 5000

# Warning: The database defined as “test” will be erased and

# re-generated from your development database when you run “rake”.

# Do not set this db to the same as development or production.

test:  
adapter: sqlite3  
database: db/test.sqlite3  
pool: 5  
timeout: 5000

production:  
adapter: sqlite3  
database: db/production.sqlite3  
pool: 5  
timeout: 5000

Thank you! That worked.

P.S. used the tutorial for Mac OS X at:
