为了更好地管理我的应用程序中所需的 gem，我创建了一个 Gemfile 组，名为 :iron:
group :default, :iron do
gem "activerecord", require: 'active_record
gem 'mysql2'
gem 'aws-sdk'
gem 'yajl-ruby'
gem 'hashie'
gem 'require_all'
end
这将有助于巩固钢铁工人所需的宝石。我的 .worker 文件现在如下：
gemfile '../Gemfile', 'iron'
而不是单独列出所有的宝石：
gem "activerecord"
gem 'mysql2'
...
不幸的是，这将我的远程构建时间从 1 分钟增加到 10 分钟。输出试图包含更多的 gem，似乎冒泡了嵌套的依赖项：
前：
------> Creating code package
Found workerfile with path='iron_job.worker'
Detected exec with path='iron_job_bootstrapper.rb' and args='{}'
Merging dir with path='../app/models' and dest=''

Adding ruby gem dependency with name='yajl-ruby' and version='>= 0'
Adding ruby gem dependency with name='hashie' and version='>= 0'
Adding ruby gem dependency with name='require_all' and version='>= 0'
后：

Adding ruby gem dependency with name='require_all' and version='1.3.1'
Adding ruby gem dependency with name='yajl-ruby' and version='1.1.0'
这个输出是本地的，但是 IronWorker 服务的时间更长，因为它不止一次地重新安装 gems（卸载然后重新安装 bundler）。下面的日志有详细信息。

从那以后，我们回到了一个 .worker 文件，它只是列出了我们需要的 gem，而不是调用 gemfile "Gemfile"、"iron"。任何有关如何在不重新安装捆绑程序的情况下使用 gemfile 并有 10m 上传时间的帮助将不胜感激！
谢谢。
编辑
添加完整的 Gemfile。请注意，我们不想拉入 :default 组中的所有宝石。这对我们的工人来说太过分了。我们只想要：铁。
