I am a beginner in ruby on rails and I got the error (rake aborted file not found --sqlite) while using the rake command. am using mysql as my database server.. what could be the problem???
You're not giving much detail about your environment (operating system, version of rails, etc.)
But my guess is you need to create your rails app with "rails myapp -d mysql". By default Rails 2.02 will generate a sqlite-specific database.yml file for you, not mysql.

Does your database.yml file say you are using mysql?

Hello, I'm in a similar situation.
running on FreeBSD 7, Ruby 1.8, Rails 2.0.2 new install, RoR beginner... Using WEBrick server
after reading the note above - rebuilt app with rails newappname - d mysql - moved app/controller and view for my app to the new rails directory
still getting complaints from activerecord 2.0.2 that sqlite3 is not installed. Now as it happens it is installed, but I want to use mysql. config/database.yml is configured for mysql. I've tried update/uninstall/install on activerecord with no apparent change in result.
Any ideas on how to get past this? thx, Dennis
Please post your gem list and the contents of your config/ database.yml...

gem install sqlite blows up due to missing files that it can't find on either the file system or the net...
sigh...
What's the stack trace when activerecord tells you it couldn't find sqlite3?
