I’m just starting my first rails app and I can’t figure out this error.  
It’s got something to do with connecting to sqlite3…Here’s the  
application trace:

Any ideas what’s going on?

Thanks for your help!

For what it’s worth, I also discovered that this error shows up when I  
try to generate a scaffold:

eric$ ruby script/generate scaffold Education  
exists app/controllers/  
exists app/helpers/  
exists app/views/education  
exists test/functional/  
dependency model  
exists app/models/  
exists test/unit/  
exists test/fixtures/  
identical app/models/education.rb  
identical test/unit/education\_test.rb  
identical test/fixtures/education.yml  
uninitialized constant API

I decided that this might have to do with my install, so (on OSX) I  
installed Locomotive, and when I ran my application through  
Locomotive/lighttpd instead of WEBrick (script/server), I didn’t get the  
application error from the initial post. I did, however, still get the  
scaffolding error in this post. So I went on to install mysql via MAMP,  
and after reconfiguring for mysql, the application seems to work fine.  
Scaffolds generate, no application error messages.

Dunno. But I’m just as happy to be using mysql now that it’s installed.
