運行heroku rake db時出現問題：migrate getting rake aborted！錯誤

我能夠推到heroku，現在我需要遷移數據庫，但我得到的錯誤耙中止！運行heroku rake db時出現問題：migrate getting rake aborted！錯誤

我跑的命令Heroku的耙分貝：遷移和我的命令行的錯誤是

WARNING: `heroku rake` has been deprecated. Please use `heroku run rake` instead. 
Running `rake db:migrate` attached to terminal... up, run.6184 
rake aborted! 
uninitialized constant MiniTest::Rails 
/app/vendor/bundle/ruby/2.0.0/gems/minitest-4.7.5/lib/minitest/unit.rb:19:in `const_missing' 
/app/Rakefile:9:in `<top (required)>' 
(See full trace by running task with --trace)

所以後來我跑命令

Running `rake db:migrate` attached to terminal... up, run.8495 
rake aborted! 
uninitialized constant MiniTest::Rails 
/app/vendor/bundle/ruby/2.0.0/gems/minitest-4.7.5/lib/minitest/unit.rb:19:in `const_missing' 
/app/Rakefile:9:in `<top (required)>' 
(See full trace by running task with --trace)

，這裏是我的Rakefile

#!/usr/bin/env rake 
# Add your own tasks in files placed in lib/tasks ending in .rake, 
# for example lib/tasks/capistrano.rake, and they will automatically be available to Rake. 

require File.expand_path('../config/application', __FILE__) 
require 'rake/dsl_definition' 
require 'rake' 

Portfolio::Application.load_tasks 

MiniTest::Rails::Testing.default_tasks << "features"

副本

這裏也是我的Gemfile的副本

group :development, :test do 
     gem "minitest-rails" 
     gem 'sqlite3' 
    end 

    group :production do 
     gem 'pg' 
     gem 'rails_12factor' 
    end 




    group :test do 
     gem "minitest-rails-capybara" 
    end 

    # Gems used only for assets and not required 
    # in production environments by default. 
    group :assets do 
     gem 'sass-rails', '~> 3.2.3' 
     gem 'coffee-rails', '~> 3.2.1' 

     # See https://github.com/sstephenson/execjs#readme for more supported runtimes 
     # gem 'therubyracer', :platforms => :ruby 

     gem 'uglifier', '>= 1.0.3' 
    end 

    gem 'jquery-rails' 

    # To use ActiveModel has_secure_password 
    # gem 'bcrypt-ruby', '~> 3.0.0' 

    # To use Jbuilder templates for JSON 
    # gem 'jbuilder' 

    # Use unicorn as the app server 
    # gem 'unicorn' 

    # Deploy with Capistrano 
    # gem 'capistrano' 

    # To use debugger 
    # gem 'debugger'

任何人都確定我的問題是什麼，爲什麼我無法遷移爲heroku？

jeanaux和rb512絕對是在正確的軌道上，謝謝！

Heroku的使用Rakefile，你不能引用MiniTest:Rails模塊，因爲只被列入創業板在測試和開發羣體Gemfile

我必須做什麼的測試和開發環境是體檢，讓Rake再次工作。

if (Rails.env == "test" || Rails.env == "development") 
    MiniTest::Rails::Testing.default_tasks << "features" 
end

謝謝@Ivanoats你的文章工作很好！ rb512和jeanaux你幫助與heroku，但它停止了在開發工作，現在它在兩個工程！ –

你們，我錯過了開發檢查，趕上ivanoats – rb512

另類：包括最小的鐵軌寶石無處不在。查看寶石創建者@blowmage的評論：https：//twitter.com/blowmage/status/387034628734738433 – brookr

你的gemfile文件只在測試組中有minitest，這很好，但是你的rake文件試圖使用MiniTest類。試試這個：

if Rails.env == "test" 
    MiniTest::Rails::Testing.default_tasks << "features" 
end

這裏的原因：uninitialized constant MiniTest::Rails

你僅用於開發和測試環境指定MINITEST護欄。默認情況下，heroku在生產環境中運行應用程序，並且您沒有用於製作產品的minitest-rails。

和條件，運行測試任務只用於測試：

MINITEST ::滑軌:: Testing.default_tasks < < 「功能」如果Rails.env == '測試'
