【问题描述】：

当我运行brew install php@7.4 时，出现以下错误。

Error: php@7.4: /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core/Aliases/php@7.4:1: syntax error, unexpected ..
../Formula/php.rb
^~
/usr/local/Homebrew/Library/Taps/homebrew/homebrew-core/Aliases/php@7.4:1: unknown regexp options - php
ALT01979:Homebrew hc641j$

brew install php@7.4.10

在下面给出这个错误。

Error: No available formula with the name "php@7.4.10" 
==> Searching for a previously deleted formula (in the last month)...
Warning: homebrew/core is shallow clone. To get complete history run:
  git -C "$(brew --repo homebrew/core)" fetch --unshallow

Error: No previously deleted formula found.
==> Searching for similarly named formulae...
Error: No similarly named formulae found.
==> Searching taps...
==> Searching taps on GitHub...
Error: No formulae found in taps.

当我尝试安装 php 时它可以工作，但我需要专门安装 7.4。

试试这个stitcher.io/blog/php-74-upgrade-macbrew update brew upgrade php

标签： php homebrew

【解决方案1】：

homebrew-core 没有 php@7.4 的别名，这就是为什么你不能使用brew install php@7.4，但你应该可以使用brew install php 来安装 php 7.4.10

版本检查测试：

$ php --version
