brew - Version value must be a s

Homebrew不兼容（只支持macOS的正式发行版本）。报错如下：

Traceback (most recent call last):
    11: from /usr/local/Homebrew/Library/Homebrew/brew.rb:23:in `<main>'

两种解决方案：

1、安装最新版本的Command Line tools, 前往此处下载

2、Version写死

打开报错路径文件

cd /usr/local/Homebrew/Library/Homebrew
open version.rb

找到版本判断逻辑并替换

@version = val.to_str
替换为
@version = '<SystemVersion>'
