我很抱歉，我知道直接代码转储不是提问的好方法，但这是我的第一个Ruby脚本，我甚至无法调试它，因为我＆＃39;我得到了奇怪的错误。我正在使用git运行我的脚本，它只是直接破坏了......我不理解什么？我错过了宝石安装或什么？即使是指向相关阅读的指针也会受到高度赞赏。
正如我收到的错误一样：
$ hello.rb
./hello.rb: line 8: class: command not found
./hello.rb: line 10: attr_accessor: command not found
./hello.rb: line 11: syntax error near unexpected token `('
./hello.rb: line 11: ` def initialize(name,cash,zip)'
如果我将循环从底部移动到顶部：
$ hello.rb
./hello.rb: line 6: syntax error near unexpected token `('
./hello.rb: line 6: `def main()'
hello.rb的：

这些是来自某些shell的错误消息，而不是Ruby。你有什么Ruby脚本。您需要使用Ruby运行Ruby脚本。你的shell并不了解Ruby，它只能理解自己的语言。
