将Ruby on Rails部署到Heroku

Question

I am trying to upload RoR application to Heroku.

OS - Ubuntu, ruby version - 2.2.2p95, rails version - 4.2.1, database - PostgreSQL, installed RoR via BrightBox (Tutorial from treehouse), using git push heroku master to upload.

On the local server app works fine. When I push it to heroku, it gives out an error:

The page you were looking for doesn't exist.
You may have mistyped the address or the page may have moved.
If you are the application owner check the logs for more information.

Log files say:

/usr/bin/env: ruby2.2: No such file or directory

I've tried all the possible variants, I could find on the Internet:

rake rails:update:bin

Remove bin from ~/.gitignore (But there is no such file)

heroku config:set PATH=bin:vendor/bundle/ruby/2.2.2/bin:/usr/local/bin:/usr/bin:/bin

Adding this to the GemFile: ruby '2.2.2'

Changed #!/usr/bin/env ruby2.2(.2 (not sure about ".2")) to #!/usr/bin/env ruby (in bin/rake, bin/bundle and bin/rails)

heroku run rails db:migrate
rake rails:update:bin

ln -s /usr/bin/nodejs /usr/bin/node

To upload to heroku, I've configured git, after that logged in heroku, after that "heroku create", after that "git push heroku master", then "heroku open"

And many others... Any ideas how to solve that problem?

Answer 1

您是否已安装gem rails12_factor和config.assets.compile = true ？

Answer 2

Not sure you mistyped or something else. but heroku run rails db:migrate will not work it should be heroku run rake db:migrate . It might be because you don't have root page. Precompile issue etc.

Run heroku logs -a app_name to see actual logs.
