刚做了一个brew install graphviz山狮这给了我这个错误
错误：执行失败：make install (graphviz.rb:47)
以为我会卸载它，所以跑了brew uninstall graphviz但是得到了
错误：没有这样的小桶：/usr/local/Cellar/graphviz
然后以为我会尝试brew doctor，但它给了我这个错误：
Warning: Unbrewed dylibs were found in /usr/local/lib.

building Homebrew formulae, and may need to be deleted.

任何想法如何解决这一问题？
