I’ve always thought the sqlite3-ruby gem is needed for Rails apps to
use SQLite3 databases, until the other day.
I set up a VM running Ubuntu 9.0.4, 32-bit server edition with Rails
2.2.2 to host an app I had written (by the way, the VM was
surprisingly easier to setup than the Mac it replaced).
I had neglected to install the sqlite3-ruby gem on the VM, which I had
installed on the Mac, but my app runs just fine on the VM anyway.
If someone can enlighten me, I’d appreciate it.
