如何判断我是否正确安装了 Homebrew？

Question

不久前，我在 Mac 上安装了 Homebrew，我担心我安装不当，导致 Brew 无法正常工作。我可以从终端运行某种命令来检查一切是否正常工作？

我担心它设置不正确有两个原因：

1. 我正在观看本教程，他在其中运行命令brew search，并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.这正常吗？
2. 当我运行brew命令时，比从终端运行其他命令时花费的时间要长得多（可能需要3秒）。这是正常的吗？

Answer 1

brew --version将是检查软件是否安装成功的基本且最简单的方法。

\n

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

对于brew命令，您可以运行帮助来了解可以尝试的更多选项，如下所示

\n

$ brew search --help\nUsage: brew search, -S [options] text|/regex/ [...]\n\nPerform a substring search of cask tokens and formula names for text.

例如，如果我想安装go，我可以这样做brew search go：

\n

$ brew search node\n==> Formulae\nheroku/brew/heroku-node \xe2\x9c\x94            node \xe2\x9c\x94                               node@10                              node_exporter                        nodenv\nlibbitcoin-node                      node-build                           node@12                              nodebrew                             ode\nllnode                               node-sass                            node@14                              nodeenv\n==> Casks\nfont-ubuntu-mono-derivative-powerline                         nodebox                                                       nodeclipse\nnodebox                                                       nodeclipse\n\nIf you meant "node" specifically:\nIt was migrated from homebrew/cask to homebrew/core.\n
