Gem::loaderror: When Trying To Deploy On Heroku - Rails 4

I am trying to deploy an app (just a simple app from a Rails tutorial) to heroku but it keeps giving me the same error message. I use the command: git push heroku master It starts

Solution 1:

Kirti is right in saying that Heroku does not support sqlite as adapter,

do the following

in the Gemfile:

group :production, :stagingdo
  gem 'pg'end

group :development, :testdo
  gem 'sqlite3'end

in database.yml

production:adapter:postgresqldatabase:name_of_your_dbpool:5timeout:5000

Solution 2:

SQLite is not intended as a production grade database. Instead Heroku provides production grade PostgreSQL databases as a service.
