更新:由于此答案已被接受，除非 OP 接受另一个答案，否则我无法删除它，但人们通过 Google 搜索登陆此处，请参阅其他答案.这与其说是回答，不如说是口齿伶俐.Ruby 社区有很棒的工具可以像 Rubocop 和朋友一样进行各种静态代码分析.至少，ruby -c 将完成 OP 想要的.

UPDATE: Since this answer was accepted, I can't delete it unless the OP accepts another answer but people landing here through Google search, please see the other answers. This was more of a tongue in cheek remark than an answer. Ruby community has wonderful tools for doing all kinds of static code analysis like Rubocop and friends. At the bare minimum, ruby -c will accomplish what the OP wanted.
