我发现我使用require加载 Sinatra Web 框架之类的东西没有问题，但我似乎无法使用require加载我自己的自定义代码？

例如我有两个文件：

  1. 测试1.rb
  2. test2.rb

'test1.rb' 的内容是：

#!/usr/bin/env ruby
require 'test2'

'test2.rb' 的内容是：

class String
    def vowels
        self.scan(/[aeiou]/i)
    end
end

如果我尝试运行，ruby test1.rb则会收到以下错误...

/Users/<username>/.rvm/rubies/ruby-1.9.3-p125/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file -- test2 (LoadError)
    from /Users/<username>/.rvm/rubies/ruby-1.9.3-p125/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require'
    from test1.rb:3:in `<main>'

然后我注意到，如果我尝试使用shotgungem 加载 Web 服务器，那么我会得到一个不同但更详细的错误堆栈跟踪......

Boot Error
Something went wrong while loading test1.rb
LoadError: cannot load such file -- test2

我不确定是什么问题？

任何帮助表示赞赏。

谢谢。

当前目录（相对于主 ruby​​ 文件）不是加载路径（require查找的路径集）的一部分。因此，您要么需要将其添加到加载路径（最好通过调用 ruby​​ as 来完成ruby -I. test1.rb），要么通过 usingrequire "./test2.rb"或通过 using require_relative "test2.rb"，这需要相对于文件目录的文件。
