cask, brew-cask 时出错

Question

我想在 OS X 10.11.6

中安装搜索引擎 elasticsearch

在我的命令行中

brew install elasticsearch

它显示错误（需要 java）

elasticsearch: Java 1.7+ is required to install this formula.
You can install with Homebrew Cask:
  brew install Caskroom/cask/java

You can download from:
  http://www.oracle.com/technetwork/java/javase/downloads/index.html
Error: An unsatisfied requirement failed this build.

我流这个博客的解决方案

brew tap caskroom/cask

并显示

Warning: Tap caskroom/cask already tapped.

第二个命令

brew install brew-cask

显示错误

Error: No available formula with the name "brew-cask"
==> Searching for similarly named formulae...
Error: No similarly named formulae found.
==> Searching taps...
This formula was found in a tap:
Caskroom/cask/brew-cask-completion
To install it, run:
  brew install Caskroom/cask/brew-cask-completion
==> You haven't updated Homebrew in a while.
A formula for brew-cask might have been added recently.
Run `brew update` to get the latest Homebrew updates!

然后我安装 java

brew cask install java

但是 cask 没有安装

==> brew cask install Caskroom/cask/brew-cask-completion
Error: Unknown command: cask

和一些博客给我一些建议

brew upgrade brew-cask

显示错误

Error: No available formula with the name "brew-cask"

如果我不明白为什么我的 mac 找不到木桶...

请有人帮助我

Answer 1

问题已解决我需要更新

brew update

Answer 2

试试这个对我有用。

我以为是 brew update install package 命令，

brew install --cask java
