Heroku Rails安装程序“您正在查找的页面不存在。” [英] Heroku Rails Setup "The page you were looking for doesn't exist."

问题描述

我遵循

I'm following this Rails tutorial. When I run rails server locally, I can see the "Welcome Aboard" page. However, when deploying to Heroku, it shows "The page you were looking for doesn't exist." I've searched around but couldn't find anything to solve my problem. Below are my steps:

rails new first_app  

Make this change to Gemfile:

group :production do
    gem 'pg'
end

group :development do 
    gem 'sqlite3' 
end

Then,

bundle update
bundle install
bundle install --without production
rake assets:precompile

git init
git add .
git commit -m "initial commit"

heroku login
heroku create
git push heroku master
heroku open

At this point it opens the address for the heroku app and gives the "doesn't exist" error. When checking 'heroku logs' it shows the status=404 of my visit:

解决方案

Beginning in Rails 4, the "Welcome Aboard" page is no longer a static page located in the public directory, it is a smoke page located within the Rails framework itself. This page will only be shown in the development mode, so when you've deployed to Heroku and are running in production mode, you won't get an automatic start page. You'll need to add a root route otherwise you'll get the error you are seeing.
