系統(tǒng) macOS Big Sur 版本 11.0
芯片Apple M1

brew運(yùn)行任何命令都會(huì)報(bào)錯(cuò)，原因是 brew 只支持正式發(fā)行版。

~ brew install svn
Traceback (most recent call last):

/usr/local/Homebrew/Library/Homebrew/version.rb:368:in `initialize': Version value must be a string; got a NilClass () (TypeError)

解決方法
從錯(cuò)誤中可以看得出來(lái) 是version.rb 這個(gè)文件的368行報(bào)錯(cuò)，我們可以直接給他個(gè)寫死的版本 即可，讓他認(rèn)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(yǔ)句注釋掉，然后 version 指定為 10.14.1。
再次運(yùn)行就不會(huì)報(bào)錯(cuò)了。
記得最好不要更新brew，不然代碼可能會(huì)被覆蓋掉。下次還得改一遍。
