about sqlite install

Hell: I have the rails 2.1 installed and made an app to run it locally.But when inputting the url,the browser show the following errors:   Could not find the file: sqlite3.dll   This error occurred while loading the following files:    sqlite3/driver/dl/driver    sqlite3/driver/dl/api

I have installed the sqlite3 through the command: gem install sqlite3-ruby

The command line told me this task finished.So why got the above error and how to manage it?

I have resoved this problem.
