Quoting David James <rails-mailing-list@andreas-s.net>:
Experienced developer here just attacking Ruby on Rails.
So, I bought myself a book (Beginning Ruby on Rails - Holzner) and proceeded to follow the tutorial for the first project. I start up Webrick which seems to be working properly. Then, after editing/creating the two simple files per the instructions I point my browser at http://localhost:3000/app/greeting. Instead of seeing the result I was expecting, I got:
===================== We're sorry, but something went wrong. We've been notified about this issue and we'll take a look at it shortly.
Now, I've actually tried a couple of different tutorials with the same result. When this is displayed in my browser, I also get this webrick logging (below) in the dos box it is running in, but have no idea what it means.
Since I've been stuck on this a couple days if anyone can point me to an approach to getting past this I will greatly appreciate it. Everything I've done with the tutorial seems to have worked correctly through this process -- the rails command, the generate controller, starting webrick, all seem straightforward and like they're working as expected.
TIA
Dave

[snip]
The sqlite3 gem is not installed. This is now the default database adapter. Rails is a fast moving target and tutorials are quickly out of date. It used to be MySQL (at least on Linux and I think MacOS). If you have installed a different database adapter, set the correct value in config\database.yml. Otherwise, install the sqlite3.
