“无法加载这样的文件-厨师/休息”当“需要'厨师/休息'”时

问题描述：

尝试编写第一个程序以通过API访问Chef服务器。以下> https://docs.chef.io/api_chef_server.html#examples 上的示例程序>应该有两行代码包含 chef :: rest 库。

Trying to write first program to access chef server via API. Following example program on https://docs.chef.io/api_chef_server.html#examples there supposed to be two lines of code to include chef::rest library.

require 'chef'
require 'chef/rest'

但是代码失败并出现错误

but the code failed with error

Traceback (most recent call last):
        2: from ./rest.rb:4:in `<main>'
        1: from /opt/chef/embedded/lib/ruby/site_ruby/2.5.0/rubygems/core_ext/kernel_require.rb:54:in `require'
/opt/chef/embedded/lib/ruby/site_ruby/2.5.0/rubygems/core_ext/kernel_require.rb:54:in `require': cannot load such file -- chef/rest (LoadError)

Chef客户端版本：14.12.9-1
操作系统版本：Ubuntu 16.04 LTS

Chef client version: 14.12.9-1 OS Version: Ubuntu 16.04 LTS

是否缺少任何步骤？

答

您没有分享是否使用厨师库作为ap您的食谱的艺术性或作为依赖厨师库的另一个程序的一部分。

you did not share whether you use chef libraries as a part of your cookbooks or as a part of another program that depended on the chef libraries.

如果您是第二种情况，即在食谱上下文之外，则确保您正在使用Gemfile来管理厨师库需求，然后使用捆绑程序执行程序。

if you are at the second case, i.e. outside of a cookbook context, then make sure that you are using Gemfile to manage your chef libraries requirement, then execute your program using bundler.

如您所见， Chef :: Rest 已弃用

as you can see, Chef::Rest is deprecated

Chef :: REST 类将被删除。 Chef :: REST 在12.7.2中已弃用，并将在Chef 13中删除。

The Chef::REST class will be removed. Chef::REST was deprecated in 12.7.2, and will be removed in Chef 13.

如果编写代码设计为在Chef内部运行（例如在食谱或小刀插件中），过渡到使用 Chef :: ServerAPI 。在大多数情况下，这就像创建一个 Chef :: ServerAPI 实例而不是一个 Chef :: REST 实例一样简单。

If writing code designed to be run internally to Chef, for example in a cookbook or a knife plugin, transition to using Chef::ServerAPI. In most cases this is as simple as creating a Chef::ServerAPI instance rather than a Chef::REST one.

如果要编写代码与其他代码与Chef Server进行交互，请移至 chef-api gem。

If writing code to interact with a Chef Server from other code, move to the chef-api gem.

所以我假设您使用的是旧厨师版，因此，我将使用厨师版12.6：

so i assume that you are using an old chef version, so for the remedy i will be using chef version 12.6:

$ cat Gemfile
# frozen_string_literal: true

source "https://rubygems.org"

gem 'chef', '12.6.0'

$ cat foo.rb
require 'chef'
require 'chef/rest'

$ bundle install
...
Bundle complete! 1 Gemfile dependency, 46 gems now installed.

$ bundle exec ruby foo.rb
