I just started the ruby.railstutorial.org book by Michael Hartl and have been working through the first chapter. I am using mac book OS X, Terminal, and Sublime Text. Everything has gone according to plan, up until it was time to test deployment to Heroku. I am able to connect to Heroku and run the
$ git push heroku master command. But the deployment fails:
Installing sqlite3 (1.3.5) with native extensions Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension. /usr/local/bin/ruby extconf.rb checking for sqlite3.h... no sqlite3.h is missing. Try 'port install sqlite3 +universal' or 'yum install sqlite-devel' and check your shared library search path (the location where your sqlite3 shared library is located). *** extconf.rb failed *** Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers. Check the mkmf.log file for more details. You may need configuration options. Provided configuration options: An error occurred while installing sqlite3 (1.3.5), and Bundler cannot continue. Make sure that `gem install sqlite3 -v '1.3.5'` succeeds before bundling. ! ! Failed to install gems via Bundler. ! ! Detected sqlite3 gem which is not supported on Heroku. ! http://devcenter.heroku.com/articles/how-do-i-use-sqlite3-for-development ! ! Heroku push rejected, failed to compile Ruby/rails app
Here is my Gemfile
source 'https://rubygems.org' gem 'rails', '3.2.8' # Bundle edge Rails instead: # gem 'rails', :git => 'git://github.com/rails/rails.git' group :development, :test do gem 'sqlite3', '1.3.5' end # Gems used only for assets and not required # in production environments by default. group :assets do gem 'sass-rails', '~> 3.2.5' gem 'coffee-rails', '~> 3.2.2' # See https://github.com/sstephenson/execjs#readme for more supported runtimes # gem 'therubyracer', :platforms => :ruby gem 'uglifier', '>= 1.2.3' end gem 'jquery-rails', '2.0.2' group :production do gem 'pg', '0.12.2' end # To use ActiveModel has_secure_password # gem 'bcrypt-ruby', '~> 3.0.0' # To use Jbuilder templates for JSON # gem 'jbuilder' # Use unicorn as the app server # gem 'unicorn' # Deploy with Capistrano # gem 'capistrano' # To use debugger # gem 'debugger'
I have sqlite3 designated for development and not production, so I thought Heroku would just ignore it all together, but that does not seem to be the case.
Also, when i create the bundle i am using $ bundle install --without production
I know that some people has suggested to just install PG and use that, but I really want to stick to the tutorial as much as possible, before I venture out and try a different approach.
I am a bit lost at the moment, and not sure how to proceed from here. Any help that you can provide would be most appreciated.
Heroku can't install the sqlite3 gem, for whatever reason. But you can tell
bundler that it shouldn't be trying to except when developing.
gem 'sqlite3' with:
group :development, :test do gem 'sqlite3' end group :production do gem 'pg' end
Then bundler on heroku, running as
production, won't try to install it.
