Question

我正在使用Chef 11.10.0。

我实现了一个名为MyCookbookFile的新资源，它继承了Chef :: Resource :: CookbookFile。

而且，我此刻不会更改提供者（因此将使用Chef :: Provider :: CookbookFile）。

require 'chef/resource/cookbook_file'
require 'chef/mixin/securable'

class Chef
  class Resource
    class MyCookbookFile < Chef::Resource::CookbookFile
      include Chef::Mixin::Securable

      provides :my_cookbook_file, :on_platforms => :all

      # more codes here...

    end
  end
end

我遇到了以下错误：

我试着在我的食谱中打印并检查LOAD_PATH。它包括：

/opt/chef/embedded/lib/ruby/gems/1.9.1/gems/chef-11.10.0/bin/../lib

图书馆应该到位：

[root@localhost /]$ ll /opt/chef/embedded/lib/ruby/gems/1.9.1/gems/chef-11.10.0/lib/chef/resource/cookbook_file.rb 
-rw-r--r-- 1 root root 1598 Feb  6 17:22 /opt/chef/embedded/lib/ruby/gems/1.9.1/gems/chef-11.10.0/lib/chef/resource/cookbook_file.rb

Answer 1

您应该在 Chef :: Resource :: CookbookFile 之前添加 :: 。

 class MyCookbookFile < ::Chef::Resource::CookbookFile

将 my_cookbook_file.rb 移动到cookbook的 libraries 文件夹，因为你使用纯Ruby而不是LWRP语法。

Answer 2

变化：

class MyCookbookFile < Chef::Resource::CookbookFile

为：

class MyCookbookFile < ::Chef::Resource::CookbookFile

运行chef-client </class时遇到“未初始化的常量＃<class：0x8d78f18> :: Chef :: Resource :: CookbookFile”：0x8d78f18>
