ruby-on-rails - rake 数据库 :migrate gives error

Question

上周我一直在尝试设置以下配置:安装干净的 Centos 7 的 VPS。运行Redmine的Ruby on Rails，都是为了读出一个用bacula制作的redmine数据库的备份。

现在请注意，我来自图形设计/Microsoft/硬件工程背景，目前正在过渡，所以我仍然非常不熟悉我当前雇主使用的大部分堆栈，因为我在那里工作了一段时间几周。

设置 VPS 和安装 Centos7 非常简单，然后我继续安装 rbenv/httpd/bundler/rmagick/all the gems 并恢复 redmine 备份(整个安装的备份)。

现在我想运行一个 rake db:migrate 命令(只是跟随来自 redmine 和 digital ocean 的 wiki)，这发生了:

[user@machinename redmine]$ rake db:migrate
rake aborted!
ActiveRecord::AdapterNotSpecified: 'development' database is not configured. Available: ["production"]
/opt/redmine-3.1.0/lib/plugins/acts_as_activity_provider/init.rb:2:in `block in <top (required)>'
/opt/redmine-3.1.0/config/initializers/00-core_plugins.rb:12:in `eval'
/opt/redmine-3.1.0/config/initializers/00-core_plugins.rb:12:in `block in <top (required)>'
/opt/redmine-3.1.0/config/initializers/00-core_plugins.rb:2:in `each'
/opt/redmine-3.1.0/config/initializers/00-core_plugins.rb:2:in `<top (required)>'
/opt/redmine-3.1.0/config/environment.rb:14:in `<top (required)>'
Tasks: TOP => db:migrate => environment
(See full trace by running task with --trace)
[user@machinename redmine]$

如果我然后检查让我们说 00-core_plugins.rb 我似乎无法找到什么是错的。

# Loads the core plugins located in lib/plugins
Dir.glob(File.join(Rails.root, "lib/plugins/*")).sort.each do |directory|
  if File.directory?(directory)
    lib = File.join(directory, "lib")
    if File.directory?(lib)
      $:.unshift lib
      ActiveSupport::Dependencies.autoload_paths += [lib]
    end
    initializer = File.join(directory, "init.rb")
    if File.file?(initializer)
      config = RedmineApp::Application.config
      eval(File.read(initializer), binding, initializer)
    end
  end
end

如果有人可以对我做错了什么提供一些帮助/见解，我们将不胜感激。设置 redmine 和所有依赖项的独立安装程序也很好，因为我实际上只需要能够将数据库的备份导入 redmine。

  # SCM paths validation.
  #
  # You can configure a regular expression for each SCM that will be used to
  # validate the path of new repositories (eg. path entered by users with the
  # "Manage repositories" permission and path returned by reposman.rb).
  # The regexp will be wrapped with \A \z, so it must match the whole path.
  # And the regexp is case sensitive.
  #
  # You can match the project identifier by using %project% in the regexp.
  #
  # You can also set a custom hint message for each SCM that will be displayed
  # on the repository form instead of the default one.
  #
  # Examples:
  # scm_subversion_path_regexp: file:///svnpath/[a-z0-9_]+

感谢 Deepak 的建议，我在 database.yml 中添加了一个“开发”部分，但现在我收到了这个错误:

我假设你需要通过你的database.yml设置生产环境所以你需要在运行 rake db:migrate: 时指定它:

bundle exec rake db:migrate RAILS_ENV=production
