以下是错误：
$brew木桶安装崇高文本
错误：没有这样的文件或目录-酿造桶
brew cask install在当天早些时候工作，所以我希望这只是加载路径的变化影响了shell查找和运行brew cask install命令的能力。
所以，我做了一个详尽的搜索：
$ find / ( -name "brew-cask*" -type f ) -or ( -ilname "*brew-cask*" ) 2>/dev/null | grep brew-cask | xargs ls -l

最后两行看起来很有趣。。。

嗯。。。/usr/local/opt/brew-cask指向一个目录，该目录包含一个bin目录，然后包含酿造桶。。。
然后，我看了看我的装载路径。。。
$ echo $PATH
/Users/lex/.rbenv/shims:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/opt/coreutils/libexec/gnubin:/Users/lex/.rbenv/bin:/Users/lex/.rbenv/shims:/Users/lex/bin:/usr/local/opt:/usr/local/bin:/usr/bin
果不其然，在加载/usr/local/bin中的文件之前，我的PATH已经更改为加载/usr/local/opt中的文件。
其余的"可执行文件"在/usr/local/opt目录中是类似的。所以，我把它从我的道路上移开了。
我再试了一次。。。
