Heroku error : no such file to load -- sqlite3/sqlite3_native

I am using Mysql on my local mashine. I am having a problem when I tries to push the database. I have installed taps.

   Home@PC /c/rails/konkurranceportalen (master)
    $ heroku db:push
    Taps Load Error: no such file to load -- sqlite3/sqlite3_native
    You may need to install or update the taps gem to use db commands.
    On most systems this will be:

    sudo gem install taps

Updated I get the following error now:

Ruby.exe system error
The program could not be started because sqlite3.dll is missing on the computer.

My database yml:

# SQLite version 3.x
# gem install sqlite3-ruby (not necessary on OS X Leopard)
# gem 'mysql', '2.8.1'

  pool: 5
  username: root
  password: 
  socket: C:/xampp/mysql/bin/mysqld.sock
  host: 127.0.0.1

I did download sqlite.dll here http://www.sqlite.org/download.html and did paste it in ruby/bin and myapp/tmp/sockets Then I could run heroku db:push

Simply adding

gem 'sqlite3'

to my Gemfile within the 'development' group fixed it for me.

You need to install the Taps gem first. It should work automagically after that.

See if your database.yml file is correctly configured.

Or just use

$ heroku db:push mysql://root:mypass@localhost/mydb

Fill in the required details in the above command.
