ruby命令行gem不在windows中工作

Question

我最近根据这里的教程写了一个命令行gem：

http://robdodson.me/how-to-write-a-command-line-ruby-gem/

它在linux中运行良好，但出于某种原因我无法在windows中运行它。

在Windows中，我收到以下错误：

C:/Ruby193/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file -- my_gem_name (LoadError)
        from C:/Ruby193/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require'
        from C:/Ruby193/lib/ruby/gems/1.9.1/gems/my_gem_name-0.0.1/bin/importer:3:in `<top (required)>'
        from C:/Ruby193/bin/importer:23:in `load'
        from C:/Ruby193/bin/importer:23:in `<main>'

非常感谢任何见解
