运行brew doctor时出现‘ ?? Formula/serf.rb ’ 等一堆问号，好像是不清楚这些是什么文件的意思。如下图所示，去文件夹中确实有看到所列出来的文件存在。请问如何解决？
When I run brew doctor, a bunch of question marks such as ‘?? Formula/serf.rb’ appear. It seems that I don’t know what these files mean. As shown in the figure below, go to the folder and indeed see the listed files exist. How can I solve it?
brew config output?
