When I tried to deploy second part of RoR tutorial to Heroku I get this error:
1 2 3 4 5 6 7 8 9 10 11 12
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 To firstname.lastname@example.org:thawing-beyond-7283.git ! [remote rejected] master -> master (pre-receive hook declined) error: failed to push some refs to 'email@example.com:thawing-beyond-7283.git'
I searched a little bit about this error and find this stackoverflow post. But when I look more carefully on the Gemfile syntax I found a mistake. I used simply:
gem 'sqlite3', '1.3.5'
But I should have:
group :development do gem 'sqlite3', '1.3.5' end group :production do gem 'pg', '0.12.2' end
As RoR tutorial states.
