Homebrewでclangをinstallしようとするとerror


<http://tkymx83.hatenablog.com/entry/2017/04/03/231642>  
ここを参考にHome brewでclangをinstallしたいのですが

[code]

    $ brew install clang
    
    Error: No available formula with the name "clang"
    ==> Searching for a previously deleted formula...
    Error: No previously deleted formula found.
    ==> Searching for similarly named formulae...
    These similarly named formulae were found:
    clang-format ✔                                       clang-format@3.8                                     emacs-clang-complete-async
    To install one of them, run (for example):
    brew install clang-format ✔
    ==> Searching taps...
    Error: No formulae found in taps.
    
[/code]

とエラーが出ます. どう対処したら良いでしょうか.



[code]

    brew install llvm
    
[/code]
