这是什么意思?一些已安装的小桶没有配方

What does this mean? Some installed kegs have no formulae

我在输入“brew doctor”后看到了这个

Warning: Some installed kegs have no formulae! This means they were either deleted or installed with brew diy. You should find replacements for the following formulae:
python@2

这是什么意思,我该如何解决?

这只是一个警告,就像大多数“酿造医生”消息一样。 Python 2死了。您可以使用 brew uninstall python@2.

删除它
