Moved from ruby 1.8.6 to 1.8.7 and "We're sorry, but something went wrong."

I’m a windows user, and I was using ruby 1.8.6 installer over at All was working well, but I decided to give ruby
1.8.7 a try. I uninstalled 1.8.6, downloaded and installed ruby 1.8.7
from rubyinstaller, reinstalled rails and all of my gems, and copied
over sqlite3.def and sqlite3.dll to the Ruby/bin.

I then my start my server (just using webrick for now, same as
before), I get the following message: “We’re sorry, but something went
wrong.” whenever I try to load up my app on my local machine.

What am I doing wrong?
I’ve searched and I can’t figure it out.

Nevermind. I’m an idiot.
I forgot to install the actual sqlite3 GEM.
gem install sqlite3-ruby --source

Problem solved, and sorry to waste a post.
