用一些需要代码测试我的类源代码，我不断收到以下错误：
“D:/ruby193/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in 'require': 无法从 D:/Ruby193/lib 加载此类文件 -- ./xxx.rb (LoadError) /ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in 'require' from xxx.rb:1:in ''
这是我用来测试我的代码的代码：
require "./proj6colecio.rb.txt"
print " "
guitar = Guitar.new("Stratocaster", "Fender", "Solid Body", 6, "Black")
print "Guitar Name: #{guitar.name}\n"
print "Guitar Brand: #{guitar.brand}\n"
print "Guitar Type: #{guitar.type}\n"
print "Number of Strings: #{guitar.strings}\n"
print "Guitar Color: #{guitar.color}\n"
print guitar, "\n"
还没有真正接受过 ruby on rails 错误的教育，因为我是一名仍在学习编程基础知识的学生。
非常感谢任何反馈
