Rubygem 在“elasticsearch-transport”安装过程中使用了错误的依赖项

Question

当我为 td-agent 安装 elasticsearch-transport 时，在 td-agent-gem install elasticsearch-transport -v2.0.0.pre 命令后出现以下错误：

这是 td-agent env 的输出：

看起来在安装过程中 gem 正在尝试安装错误的依赖项 (system_timer)，根据 Gemspec。实际上，当我使用 td-agent-gem fetch elasticsearch-transport -v2.0.0.pre 下载 gem 时，解压它 (td-agent-gem unpack elasticsearch-transport-2.0.0.pre.gem) 然后重新构建它 (td-agent-gem build elasticsearch-transport.gemspec) 我得到了不同的依赖集：

$ td-agent-gem install elasticsearch-transport-2.0.0.pre.fetched.gem --explain
Gems to install:
  elasticsearch-transport-2.0.0.pre
  faraday-0.9.2
  multi_json-1.10.1
  multipart-post-2.0.0
  system_timer-1.2.4

$ td-agent-gem install elasticsearch-transport-2.0.0.pre.built.gem --explain
Gems to install:
  elasticsearch-transport-2.0.0.pre
  faraday-0.9.2
  multi_json-1.10.1
  multipart-post-2.0.0

我如何安装此 gem 之前不构建它？

好像是elasticsearch-transport的问题。我在存储库上提交了错误报告：https://github.com/elastic/elasticsearch-ruby/issues/329
