Question

我只是按照说明从github创建我自己的自制公式，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，所以我检查了自制的mongodb源代码（因为我喜欢使用自制软件的所有东西，懒惰的人啊......）：

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"

成：

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

没有更多，只是版本号，所以我复制所有源代码冷，并创建我自己的公式，但是当我运行brew命令时，我遇到了很多错误，包括：

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

我做错了吗？我对红宝石和酿造相当新鲜，谢谢

Answer 1

使用brew install ./mongo_old.rb安装（前导./特殊）;公式是Ruby代码，不能直接执行。

Formula-Cookbook是您的朋友。您也可以参考https://medium.com/ballerina-techblog/how-to-create-your-own-homebrew-package-or-formula-8dfbf8e001d3来创建新公式（免责声明：我已经写过）。

尝试以下简单步骤；

创建新公式； brew create <URLOfTheDistribution>
然后调试它； brew install --debug <NewFormula>

自制软件不能运行我自己的公式
