Heroku db:pull error "LoadError: cannot load such file -- sqlite3 (Sequel::AdapterNotFound)"

Question

I'm able to run heroku db:pull from my MacBook development environment without any issues, but when I do the command on my Windows 7 machine I get the following error

Answer 1

You probably need to install the sqlite3 gem.

Answer 2

I would try installing a couple gems:

gem install sqlite3
gem install heroku
