Question

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

以下是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），只有当Ruby版本低于1.9时才应该使用Gemspec。实际上，当我使用td-agent-gem fetch elasticsearch-transport -v2.0.0.pre下载gem时，将其解压缩（td-agent-gem unpack elasticsearch-transport-2.0.0.pre.gem）然后再次构建它（td-agent-gem build elasticsearch-transport.gemspec）我得到了不同的依赖项集：

$ 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

如何在不构建之前安装此gem？

似乎是弹性搜索 - 运输问题。我在存储库上提交了一个错误报告：https://github.com/elastic/elasticsearch-ruby/issues/329

Rubygem在“elasticsearch-transport”安装期间使用了错误的依赖项
