自制软件不能运行我自己的公式

Question

我只是按照说明从 github 创建我的 "own" 自制软件公式，遵循本教程 http://formalfriday.club/2015/01/05/creating-your-own-homebrew-tap-and-formula.html, 实际上我只是想安装 mongodb 旧版本，所以我检查了自制软件 mongodb 源代码（因为我喜欢使用自制软件的所有东西，懒人呃...）：

https://github.com/Homebrew/homebrew/blob/master/Library/Formula/mongodb.rb

我只想更改第 6 行：

 url "https://fastdl.mongodb.org/src/mongodb-src-r3.0.1.tar.gz"

进入：

 url "https://fastdl.mongodb.org/src/mongodb-src-r3.0.0.tar.gz"

仅此而已，只是版本号，所以我复制了所有的源代码，并创建了我自己的公式，但是当我运行 brew 命令时，我得到了很多错误，包括：

/usr/local/bin/mongold: line 2: require: command not found
/usr/local/bin/mongold: line 3: require: command not found

我做错了什么吗？我是 ruby 和 brew 的新手，谢谢

Answer 1

用brew install ./mongo_old.rb安装（前面的./比较特殊）；公式是 Ruby 代码，不能直接执行。
