Question

我正在创建一个gem来封装应用程序中的一大块功能。他们宝石基本上运行一个rake任务，但当我用bundle exec rake:assets:precompile运行任务时，我收到以下错误

rake aborted!
Bundler::GemRequireError: There was an error while trying to load the gem 'gem-name'.
/Users/tonyedwardspz/myprojects/westcornwallevents/config/application.rb:8:in `<top (required)>'
/Users/tonyedwardspz/myprojects/westcornwallevents/Rakefile:4:in `require'
/Users/tonyedwardspz/myprojects/westcornwallevents/Rakefile:4:in `<top (required)>'
NameError: uninitialized constant GemName::Rails::Railtie

/Users/tonyedwardspz/myprojects/westcornwallevents/Rakefile:4:in `require'
/Users/tonyedwardspz/myprojects/westcornwallevents/Rakefile:4:in `<top (required)>'

与铁路相关的模块的代码是：

require 'rails'

module GemName
  module Rails
    class Railtie < Rails::Railtie
      railtie_name :gem_name

      rake_tasks do
        load "tasks/gem_name.rake"
      end
    end
  end
end

为什么我收到此错误的任何想法？

Answer 1

错误在类定义的语法中。如下更新代码将允许rake任务运行。

class Railtie < Rails::Railtie

到

class Railtie < ::Rails::Railtie

NameError：未初始化的常量GemName :: Rails :: Railtie
