Question

我正在使用从Rails 3生成的引擎，现在当我尝试从Rails运行发电机时，它要求我生成一个新项目。

很明显，无法找到导轨调用ActiveRecord所需的结构，但是我不知道如何修补该问题

rails g migration adding-active-boolean-to-types-and-statuses

产生此：

Usage:
  rails new APP_PATH [options]

Options:
  -r, [--ruby=PATH]                                      # Path to the Ruby binary of your choice
                                                         # Default: /System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/bin/ruby
  -m, [--template=TEMPLATE]                              # Path to some application template (can be a filesystem path or URL)
      [--skip-gemfile], [--no-skip-gemfile]              # Don't create a Gemfile
  -B, [--skip-bundle], [--no-skip-bundle]                # Don't run bundle install
  -G, [--skip-git], [--no-skip-git]                      # Skip .gitignore file
      [--skip-keeps], [--no-skip-keeps]                  # Skip source control .keep files

我尝试添加特定路径并获得相同结果：

/usr/bin/rails g migration adding-active-boolean-to-types-and-statuses

Answer 1

已解决：

原因是项目由于某种原因缺少了bin/rails文件夹。

必须生成一个新引擎，然后将文件复制/更改为指向正确的引擎文件夹。

这是任何人需要时的内容。

#!/usr/bin/env ruby
# This command will automatically be run when you run "rails" with Rails 4 gems installed from the root of your application.

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

# Set up gems listed in the Gemfile.
ENV['BUNDLE_GEMFILE'] ||= File.expand_path('../../Gemfile', __FILE__)
require 'bundler/setup' if File.exist?(ENV['BUNDLE_GEMFILE'])

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

Rails发电机无法为引擎加载
