Going up Ruby on Rails app in Heroku

Question

I completely followed what was written on that tutorial and I got this mistake:

root@neuber-HP-EliteBook-8460p:/home/neuber/node-js-sample/franca# git push heroku master
Warning: Permanently added the RSA host key for IP address '50.19.85.154' to the list of known hosts.

I didn’t file for log.

I did what the Gypsy asked and it’s wrong:

Gem files will remain installed in /var/lib/gems/1.9.1/gems/sqlite3-1.3.9 for inspection.
Results logged to /var/lib/gems/1.9.1/gems/sqlite3-1.3.9/ext/sqlite3/gem_make.out
An error occurred while installing sqlite3 (1.3.9), and Bundler cannot continue.
Make sure that `gem install sqlite3 -v '1.3.9'` succeeds before bundli

I installed Sqlite3 1.X. X and now gave the ultimate error:

 !
 !     Failed to install gems via Bundler.
 !     
 !     Detected sqlite3 gem which is not supported on Heroku.

I’m trying to climb a simple application on Node that has already run on Node shelll, but when I command Heroku create (before the deploy) gives that blue screen of application error in the browser.

Answer 1

The mistake is clear.

Gemfile.lock required. Please check it in.

Before you push again, run:

bundle install

In the case of the second pointed error, first execute this command:

gem install sqlite3 -v '1.3.9'

Then run it again bundle install.

About the Sqlite-related error, Heroku does not support Sqlite with good reason. Modify your file Gemfile to use Sqlite only in development. That is, check whether the gem is as in the following example:

group :development do
  gem 'sqlite3', '1.3.9'
end

Also check if there is a gem to Postgres (database that Heroku uses):

group :production do
  gem 'pg', '0.15.1'
end

Made these changes in your Gemfile, try again a bundle install and then the deploy.
