Question

我正在尝试加载rubywrite并运行其中一个示例，但这会给我带来以下错误： -

/usr/local/lib/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file -- rubywrite/exceptions (LoadError)
    from /usr/local/lib/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require'
    from /home/ankit/Downloads/Studies/PLI/Assignment2/RubyWrite/lib/rubywrite.rb:1:in `<top (required)>'
    from pcc.rb:4:in `require_relative'
    from pcc.rb:4:in `<main>'

我不确定需要做什么。我的Ruby版本是：

- ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-linux]

我的宝石环境是： -

Answer 1

默认情况下，当前目录不包含在库包含路径中。

您可以使用-I选项在Ruby命令行中显式添加它：

ruby -I. the_file.rb

Answer 2

使用'require_relative'并指定要包含的文件的完整路径。问题是'require'只查看Ruby库路径中的文件。另见：What is the difference between require_relative and require in Ruby?

Ruby-require抛出错误
