ruby-on-rails-3.1 - .rvm/rubies/ruby-1.9.2-p320/lib/ruby/1.9.1/net/http.rb:644:in `initialize': 没有这样的文件或目录 - getaddrinfo (Errno::ENOENT)

Question

我在尝试运行时遇到此错误:rake db:migrate、rake schema:load 和 rails s。我从 Bitbucket git 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，但没有用。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解决错误的信息？

错误号::ENOENT

No such file or directory - getaddrinfo

Answer 1

这是一个非常古老的话题，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 字符串的新对象时 http = Net::HTTP.new("http://127.0.0.1:4567")，你会得到这个错误。

您必须使用 URI 对象实例化，就像:

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