macos - 运行 brew cask install 时出错

Question

这是错误：

$ brew cask install sublime-text
错误：没有这样的文件或目录 -brew-cask

Answer 1

brew cask install当天早些时候正在工作，所以我希望这只是加载路径的更改影响了 shell 查找和运行brew cask install命令的能力。

因此，我进行了详尽的搜索：

$ find / \( -name "brew\-cask*" -type f \) -or \( -ilname "*brew-cask*" \) 2>/dev/null | grep brew-cask | xargs ls -l

lrwxr-xr-x  1 lex  admin   26 Sep  1 16:39 /usr/local/opt/brew-cask -> ../Cellar/brew-cask/0.15.0

最后两行看起来很有趣......

$ ls -l /usr/local/Cellar/brew-cask/0.15.0/bin/brew-cask.rb
-rwxr-xr-x  1 lex  wheel  197 Sep  1 16:39 /usr/local/Cellar/brew-cask/0.15.0/bin/brew-cask.rb

$ ls -l /usr/local/Cellar/brew-cask/0.15.0
total 16

嗯.../usr/local/opt/brew-cask指向一个包含 bin 目录的目录，然后包含 brew-cask...

然后，我查看了我的加载路径......

$ 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

果然，我的 PATH 已更改为在/usr/local/opt将文件加载到 /usr/local/bin 之前加载文件。

目录中的其余“可执行文件”类似 /usr/local/opt。所以，我把它从我的路径中删除了。

我又试了...
