Question

谢谢你看@这个。我相信这是一个相对简单的问题。有点长的帖子，所以你们都有任何关于我的设置和推送到Heroku的信息。我正在遵循本指南。 http://docs.railsbridge.org/intro-to-rails/deploying_to_heroku

我有这个错误：

To git@heroku.com:polar-thicket-3762.git                                                                                        
 ! [remote rejected] master -> master (pre-receive hook declined)                                                               
error: failed to push some refs to 'git@heroku.com:polar-thicket-3762.git'

当我尝试推送到Heroku时会发生这种情况。它试图预编译资产。解决方案说我需要在我的application.rb中添加这一行，以便成功推送我尝试过的。

ruby config.assets.initialize_on_precompile = false

它确实成功推动，但随后它不会通过

编译数据库

heroku run rake db:migrate

然后，当我尝试运行该命令时，它说它不会运行rake db：migrate on thread .3309，因为＆＃34; ruby＆＃34;没找到。我试着去除它前面的红宝石，然后它就不会推到heroku。

如何通过推送到Heroku来解决这个问题，并让它来编译数据库？谢谢！

了解一些事情会很有帮助，我使用Nitrous.io和Sqlite3进行开发。我的application.rb是这样的（并且下面还列出了database.yml＆amp; gemfile）

application.rb中

require File.expand_path('../boot', __FILE__)

require 'rails/all'

# Require the gems listed in Gemfile, including any gems
# you've limited to :test, :development, or :production.
Bundler.require(*Rails.groups)

module RailsBase
  class Application < Rails::Application
    # Settings in config/environments/* take precedence over those specified here.
    # Application configuration should go into files in config/initializers
    # -- all .rb files in that directory are automatically loaded.

    # Set Time.zone default to the specified zone and make Active Record auto-convert to this zone.
    # Run "rake -D time" for a list of tasks for finding time zone names. Default is UTC.
    config.time_zone = 'Central Time (US & Canada)'

    # The default locale is :en and all translations from config/locales/*.rb,yml are auto loaded.
    # config.i18n.load_path += Dir[Rails.root.join('my', 'locales', '*.{rb,yml}').to_s]
    # config.i18n.default_locale = :de

    # To push to Heroku 
    config.assets.initialize_on_precompile = false
  end
end

确保您的rails应用程序位于repo的根目录中，Gemfile存在且已正确命名。它基本上无法将您的代码库检测为受支持的项目类型之一，因此失败了。此外，即使你有一个合适的项目，确保它是回购的一部分，你已经做好了（git status将帮助你在这里，并且ls应该帮助你验证项目结构）
