我检查了关于这个主题已经提出的问题，“有很多”，但我没有找到解决方案。

我有一个相当大的任务，文件名是'sample_employee_data.rake'......所以这里是：

      namespace :db do 
        desc "Fill database with sample Employee data"
        task populate: :environment do

          @gender = ["Male", "Female"]
          @role = ["Staff", "Support", "Team_Leader", "Manager", "Director"]
          @marital_status = ["Single", "Married"]
          @primary_position = ["Household", "Job Developer", "Job Coach", 
                     "Job Support", "Personal Care"]
          @trained_position = ["Household", "Job Developer", "Job Coach", 
                     "Job Support", "Personal Care"]
          @emer_contact_relationship = ["Friend", "Brother", "Sister", "Aunt", 
                              "Uncle", "Cousin", "Nephew", "Father",
                              "Mother", "Spouse"]

          def randomDate(params={})
            years_back = params[:year_range] || 5
            latest_year = params[:year_latest]  || 0
            year = (rand * (years_back)).ceil + 
            (Time.now.year - latest_year - years_back)
             month = (rand * 12).ceil
             day = (rand * 31).ceil
             series = [date = Time.local(year, month, day)]
             if params[:series]
               params[:series].each do |some_time_after|
                 series << series.last + (rand * some_time_after).ceil
               end
               return series
              end
              date
            end

            Employee.create!(first_name:      "Shelly",
                 last_name:                   "Houghton",

我跑了：

     rake sample_employee_data.rake

我得到了这个标志：

  rake aborted!
  Don't know how to build task 'sample_employee_data.rake'
  home/me/.rvm/gems/ruby-1.9.3-p385@rails3212/bin/ruby_noexec_wrapper:14:in 'eval'
  home/me/.rvm/gems/ruby-1.9.3-p385@rails3212/bin/ruby_noexec_wrapper:14:in '<main>'

谁能发现这个问题……我为这么长的文件道歉。

谢谢。

这里发生了几件事。

当您运行时，$ rake sample_employee_data.rake您要求 rake 对您的文件进行 rake - 但 rake 会响应任务：

$ rake some_namespace:some_task_in_that_namespace

您还使用了 custom.rake file而不是传统的Rakefile- 这很好，但这意味着您需要明确告诉 rake 您没有使用它的 default Rakefile。

$ rake --rakefile your_custom_rake_file.rake some_task

所以在你的情况下，你需要像这样发出一个 rake 命令：

$ rake --rakefile sample_employee_data.rake db:populate
