【问题描述】：

我在尝试运行时遇到此错误：rake db:migrate, rake schema:load 和 rails s。我从 Bitbucket 克隆的应用程序无法使用，客户端无法提供帮助。

我已经重新安装了 ruby 和 gemset，但它没有工作。我不知道如何解决这个错误。请帮忙。是什么导致了错误，我在哪里可以找到可能帮助我修复它的信息？

Errno::ENOENT

No such file or directory - getaddrinfo

【问题讨论】：

运行 gem install bundler 没有改变任何东西 :-(
此异常是连接到某些外部站点的超时问题。它看起来像是堆栈跟踪中的新遗物。你能禁用newrelic，看看你是否还能得到它？你在防火墙后面吗？
是的，我在防火墙后面
在 newrelic.yml 中设置 agent_enabled: false 并没有修复错误。

【解决方案1】：

这是一个非常古老的线程，但我想我已经找到了问题所在。

当您使用 net/http 并尝试实例化一个传递 URL 字符串 http = Net::HTTP.new("http://127.0.0.1:4567") 的新对象时，您将收到此错误。

您必须使用 URI 对象进行实例化，就像：

uri = URI.parse("http://localhost:4567")
http = Net::HTTP.new(uri.host, uri.port)

【解决方案2】：

您是否安装了它需要的所有 gem？

你做了捆绑安装吗？

gem install bundler

bundle

【讨论】：

我怀疑问题出在 newrelic 或 copy_copter 客户端。我对吗？我一生中从未见过这样的问题。
如果您仍然怀疑，您可以尝试从 gemfile 中注释掉 gem，重新打包并尝试再次启动服务器。您可能能够找出是否是它们导致了问题，然后您可以专注于安装这些 gem 的服务器。
