Question

关于轨道上可安装引擎的问题。首先是我正在使用的版本;

$ rails -v
  Rails 3.2.1
$ ruby -v
  ruby 1.8.7 (2010-01-10 patchlevel 249) [universal-darwin11.0]

我用这个创建可安装的引擎：

$ rails plugin new testEngine --mountable
  create  
  create  README.rdoc
  create  Rakefile
  create  testEngine.gtestEnginepec
  create  MIT-LICENSE
  create  .gitignore
  create  Gemfile
  create  app
  create  app/controllers/testEngine/application_controller.rb
  create  app/helpers/testEngine/application_helper.rb
  create  app/mailers
  create  app/models
  create  app/views/layouts/testEngine/application.html.erb
  create  app/assets/images/testEngine
  create  app/assets/images/testEngine/.gitkeep
  create  config/routes.rb
  create  lib/testEngine.rb
  create  lib/tasks/testEngine_tasks.rake
  create  lib/testEngine/version.rb
  create  lib/testEngine/engine.rb
  create  app/assets/stylesheets/testEngine/application.css
  create  app/assets/javascripts/testEngine/application.js
  create  script
  create  script/rails
  create  test/test_helper.rb
  create  test/testEngine_test.rb
  append  Rakefile
  create  test/integration/navigation_test.rb
  vendor_app  test/dummy

  run  bundle install

  Your bundle is complete! Use `bundle show [gemname]` to see where a bundled gem is installed.

当我在引擎根目录中使用rails命令（而不是在dummyapp中）时，我收到以下错误：

$ rails -v
script/rails:7:in `require': no such file to load -- rails/all (LoadError)
from script/rails:7

这是我在script / rails中的rails文件：

$ cat script/rails 
#!/usr/bin/env ruby
# This command will automatically be run when you run "rails" with Rails 3 gems installed from the root of your application.

ENGINE_ROOT = File.expand_path('../..', __FILE__)
ENGINE_PATH = File.expand_path('../../lib/ems/engine', __FILE__)

require 'rails/all'
require 'rails/engine/commands'

错误表明问题源于两个导轨包含在底部。有什么办法可以解决这个问题吗？如果没有使用rails的能力，我就无法使用rails命令给我的任何工具，如脚手架等。

试试这个：

script/rails console

或者：

bundle exec rails console

rails命令在可安装的引擎根目录中不起作用
