I am facing the same problem as the below one. Does any one has any solutions? http://stackoverflow.com/questions/515639/ruby-cannot-find-sqlite3-driver-on-windows/520342 I installed Ruby 1.9.1, then rails.Then, I installed sqlite3-ruby but thats broken.So, I deleted the directory, and installed sqlite3-ruby for win version 1.2.3.But, getting error "sqlite driver not found"
You need to install the actual sqlite3 .dll for Windows.
Go to http://www.sqlite.org/download.html and download sqlitedll-3_6_13.zip and sqlite-3_6_13.zip (or whatever the most recent versions are).
Unzip both of those zipfiles. Copy sqlite3.exe to c:\windows and sqlite3.dll to c:\windows\system32
Run gem install sqlite3-ruby --no-ri --no-rdoc --version=1.2.3 --platform=mswin32 from the command line to install the SQLite3 gem (the extra flags prevent it from trying to compile some stuff that's not generally available on Windows)
I've been having the same problem.
sqlite3-ruby version 1.2.3 seems to be incompatible with Ruby 1.9. Version 1.2.4 is (maybe) compatible but a windows binary version was never released, and the maintainer has announced that he's given up on building and releasing for windows.
According to this post someone is working on a fix, but it's not there yet.
So this is going to be an unhelpful answer as so far none of my researches have found a fix that's available now. The options for getting a windows Ruby/Rails development setup today seem to be either to switch to MySQL for the development database, or move back to Ruby 1.8.7.
