brew運行任何命令都會報錯色乾，原因是 brew 只支持正式發(fā)行版勾缭。

解決方法
從錯誤中可以看得出來 是version.rb 這個文件的368行報錯顾彰，我們可以直接給他個寫死的版本 即可尽棕，讓他認為macOS是正式發(fā)行版
修改后代碼：
def initialize(val)
#raise TypeError, "Version value must be a string; got a #{val.class} (#{val})" unless val.respond_to?(:to_str)
@version = '10.14.1'
end
把拋出異常的語句注釋掉薪寓，然后 version 指定為 10.14.1且改。
再次運行就不會報錯了女蜈。
記得最好不要更新brew持舆，不然代碼可能會被覆蓋掉。下次還得改一遍伪窖。
