如何创建命令行rails generator gem？

Question

我知道如何创建一个名为rails generator的宝石：

rails g my_generator command

而且我知道如何创建可以像这样的宝石：

my_generator command

但是我不知道如何创建可以使用可执行文件调用的rails生成器。 我尝试通过创建一个lib / my_generator / cli.rb文件来尝试：

require 'thor'

module Mang
  class Cli < Thor
    include ::Rails::Generators::Base

    desc "install_gem", "install a gem"
    def install_gem
      gem 'thor', "0.18.1"
    end

  end
end

但是，尽管我在gemspec中添加了Rails作为依赖项，但仍收到以下错误。

uninitialized constant Rails (NameError)

Answer 1

修复仅是包含rails / generators / actions模块的问题。

require 'thor'
require 'rails/generators'
require 'rails/generators/actions'

module Mang
  class Cli < Thor
    include Thor::Actions
    include Rails::Generators::Actions

    desc "install_gem", "install a gem"
    def install_gem
      gem 'thor', "0.18.1"
    end

  end
end
