Unable to deploy Git repo project into Heroku

Question

I have followed below steps:

git clone git://github.com/heroku/ruby-sample.git
cd ruby-sample
heroku create
git push heroku master
heroku open

When I'm trying to run the 4th step I'm getting below error:

$ git push heroku master

Can any one help me deploy?

Answer 1

Your problem is with sqlite3 gem:

An error occurred while installing sqlite3 (1.3.8), and Bundler cannot continue. 

You have to add the pg gem to your Gemfile in production group, since Heroku uses PostgreSQL.

You can continue using sqlite3 in your development and test groups.

group :production do
  gem 'pg'
end        

group :development, :test do
  gem 'sqlite3'
end

More info here: https://devcenter.heroku.com/articles/heroku-postgresql#connecting-in-ruby

Answer 2

1)First of all you have to install sqlite3 on your os and all library sqlite-devel

2) Then in Gemfile

group :production do
 gem 'pg'
end        

group :development, :test do
 gem 'sqlite3'
end

3) bundle install

4) git add ..

5) git commit -m "..."

6) git push heroku master
