如何判断我是否正确安装了 Homebrew？答案

【问题描述】：

不久前，我在我的 Mac 上安装了 Homebrew，我担心我做错了，这会导致 Brew 无法正常工作。是否可以从终端运行某种命令来检查一切是否正常？

我担心设置不正确有两个原因：

我正在观看this tutorial，他在其中运行命令brew search，它为他提供了可以安装的软件包列表。但是当我运行命令时，我收到错误消息This command requires at least 1 text or regex argument. 这是正常的吗？
当我运行 brew 命令时，它需要的时间比我从终端运行其他命令时长得多（可能是 3 秒）。这正常吗？

brew --version 是检查软件是否安装成功的基本且最简单的方法。

$ brew --version
Homebrew 3.2.17-108-ge518ea4
Homebrew/homebrew-core (git revision 4eaec4244d4; last commit 2021-10-21)
Homebrew/homebrew-cask (git revision 4d10ee7007; last commit 2021-10-22)

对于brew 命令，您可以运行帮助以了解可以尝试的更多选项，例如

$ brew search --help

比如我要安装go，我可以做brew search go：

$ brew search node
==> Formulae
heroku/brew/heroku-node ✔            node ✔                               node@10                              node_exporter                        nodenv
libbitcoin-node                      node-build                           node@12                              nodebrew                             ode
llnode                               node-sass                            node@14                              nodeenv
==> Casks
font-ubuntu-mono-derivative-powerline                         nodebox                                                       nodeclipse
nodebox                                                       nodeclipse

If you meant "node" specifically:
It was migrated from homebrew/cask to homebrew/core.

brew doctor 还可以很好地检查您的安装。
