Question

由于我们无法访问rubygems网站，因此我们计划通过Chef cookbook在本地解决宝石及其依赖性。我们想在这个过程中添加一个rakefile。我们在Rakefile中遵循的过程如下

使用正确的版本（inspec）创建Gemfile
捆绑安装
得到Gemfile.lock＆lt; == 这是问题所在。它按字母顺序排序
我们需要按顺序创建一个具有依赖关系的数组，这样就不会在循环中安装gems。这个数组是将流程自动化到未来版本所必需的。

创建的数组遵循按字母顺序排列，在安装过程中会产生错误。

我们拥有的Gemfile是

source 'https://rubygems.org'

gem "inspec", "0.22.1"

当我们运行＆＃34;捆绑安装＆＃34;创建Gemfile.lock如下：

PLATFORMS

DEPENDENCIES
  inspec (= 0.22.1)

BUNDLED WITH
   1.11.2

Rake文件：

require 'bundler'
require 'json/pure'

  parsed_Gemfile_lock = Bundler::LockfileParser.new( File.read(File.dirname(__FILE__) + "\\Gemfile.lock"))

  # Print a Ruby Array
  parsed_Gemfile_lock.specs.each do |spec|
    gem_array = spec.to_s.split
    gem_name = gem_array[0]
    gem_version = gem_array[1]
    gem_version = gem_version.gsub(/[()]/,"'")
    print "'" + gem_name + "'=>" + gem_version + ", "
  end

结果：

让我知道是否有任何替代/简单的解决方案来解决此问题，或者指导我为此过程创建正确的Rakefile。

Answer 1

要像45个步骤一样快退，那么您需要镜像所需的宝石（https://github.com/rubygems/rubygems-mirror），然后在localhost上使用gem serve来安装它们。这似乎少了很多工作。

至于你的实际问题：你可以尝试询问Bundler维护者，但我可以保证他们会将问题关闭超出范围，因为这不是锁文件的用途。

Answer 2

我找到了另一种解决方案。

namespace :gem_attribute_array do
desc 'Generate gems attribute array'
task :generate do
puts "Generating gems attribute array and downloading all the dependent gem packages to ./vendor/cache :"
result = Mixlib::ShellOut.new('bundle package')
result.run_command
result.stdout.split("\n").each do |line|
  if line =~ /Using / or line =~ /Installing / then
    str=line.split(" ")
    gem_name=str[1]
    gem_version=str[2]
    print "'" + gem_name + "'=>'" + gem_version + "', "
  end #if loop
end # foreach loop
puts "\n" #Dummy line
end  #task
end  #namespace

Gemfile.lock应该通过依赖优先级而不是字母顺序排序
