git push heroku master: Error occurred while installing sqlite3

Question

I'm going crazy with this problem.

I'm new in Heroku and today I was trying deploy my app, but I couldn't.I could build it once, but it gave me an "internal server error ".

Error:

When I run git push heroku master , after do the commit, it returns:

Forgive me if it's a simple mistake. But it is getting me a headache.

Answer 1

Resolved

Mistake: I didn't know I must commit the changes.

1. git commit -am "comment line"
2. git push
3. git push heroku master

That's all. Thanks, @suslov

Answer 2

As stated in your error code, Heroku doesn't support sqlite3 gem:

Detected sqlite3 gem which is not supported on Heroku.

so you can't use SQLite database and should remove from your Gemfile this line:

gem 'sqlite3'

Instead Heroku supports pg gem to run your application on PostgreSQL RDBMS so you should add the following line to the Gemfile :

gem 'pg'

Then run bundle install .

And in the config/database.yml change your RDBMS settings:

default: &default
  adapter: postgresql
  pool: 5
  timeout: 5000

development:
  database: db/development

# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
  <<: *default
  database: db/test

production:
  <<: *default
  database: db/production

After that you should commit all changes and finally run:

git push heroku master

Answer 3

Are you trying to push from a local repository to hosted? Before you push I think you will have to establish a relationship by typing.

$ git remote add [alias] [url] If you got the repository with git clone, then type $git push heroku master and type $ git push again without heroku master. I hope this answers your question.

Answer 4

I may help you :

group :production do
  gem 'pg'
end
