在部署 Rails 应用程序期间，工头启动 Heroku 时出错

Question

我尝试开始使用 Rails 3.2.6 和 Heroku。我的 Ruby 版本是 1.9.3，我的 database.yml 是这样的：

development:
  adapter: postgresql
  encoding: utf8
  reconnect: false
  database: iscubeonror_development
  pool: 5
  username: rails
  password: rails
  host: localhost

test:
  adapter: postgresql
  encoding: utf8
  reconnect: false
  database: iscubeonror_test
  pool: 5
  username: root
  password:
  host: localhost

production:
  adapter: postgresql
  encoding: utf8
  reconnect: false
  database: iscubeonror_production
  pool: 5
  username: root
  password:
  host: localhost

我的 procfile 是

web: bundle exec rails server thin -p $PORT -e $RACK_ENV

我在 production.rb、development.rb 和 test.rb 上有这个：

 config.active_support.deprecation = :notify
 config.active_support.deprecation = :stderr
 config.active_support.deprecation = :stderr

最后我使用的是 windows，我的 Gemfile 是

gem 'rails', '3.2.6'
gem 'pg'
gem 'thin'
gem "foreman"

当在终端 heroku 日志 上写入时，它会给我警告

当在终端上写工头开始它给了我

D:\Kalpesh\web\iscubeonror> foreman start
19:37:27 web.1  | started with pid 3868
19:38:18 web.1  | You did not specify how you would like Rails to report depreca
tion notices for your $RACK_ENV environment, please set config.active_support.de
precation to :log, :notify or :stderr at config/environments/$RACK_ENV.rb

由于这个原因，我的瘦服务器没有启动我该怎么办
虽然我遵循所有步骤 https://devcenter.heroku.com/articles/rails3#deploy-your-application-to-heroku 请紧急回复我

Answer 1

你应该阅读：

You did not specify how you would like Rails to report depreca
tion notices for your $RACK_ENV environment, please set config.active_support.de
precation to :log, :notify or :stderr at config/environments/$RACK_ENV.rb

Answer 2

我认为你需要在 .env 中定义一些环境变量：

RACK_ENV=development
PORT=3000
