Heroku problem : The page you were looking for doesn't exist

Question

I have followed book until chapter 5 finished and it's working OK in my linux workstation when I push to Heroku, all data pushed correctly but when I try to open Heroku (http://vivid-sky-685.heroku.com)

I get a 404 message.

The page you were looking for doesn't exist. You may have mistyped the address or the page may have moved.

Below is my Gemfile for application

source 'http://rubygems.org' gem 'rails', '3.0.5' gem 'sqlite3'  group :development do   gem 'rspec-rails', '2.5.0' end  group :test do   gem 'rspec', '2.5.0'   gem 'webrat', '0.7.1'   gem 'spork', '0.9.0.rc4' end  gem 'rake','~> 0.8.7' 

Any ideas what could be going wrong?

@odin here is my heroku logs , thanks

Answer 1

I know it's an old problem but I ran into it too. I realized I didn't change the root route in config/routes.rb before pushing. Not changing it might result in a welcome page locally, but on heroku it will get the above error.

Answer 2

I got the same problem; however, after changing 1 line code of production.rb located in config/environments/production.rb from

config.assets.compile = false 

to

config.assets.compile = true 

commit the new change. Then my sample app works fine on heroku
