Ruby`require`调用在自定义代码上失败
我发现使用require来加载像Sinatra Web框架这样的东西我没有问题，但我似乎无法使用require来加载我自己的自定义代码？
例如，我有两个文件：
- test1.rb
- 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然后我得到以下错误…
/Users//.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//.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 `'
然后我注意到如果我尝试使用shotgungem加载Web服务器，那么我得到一个不同但更详细的错误堆栈跟踪…

我不确定问题是什么？
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。 所以你需要将它添加到加载路径（最好通过调用ruby作为ruby -I. test1.rb ），使用require "./test2.rb"或使用require_relative "test2.rb" ，这需要文件相对于文件的目录。
