添加扩展库安装swoole

brew tap shivammathur/extensions

# 安装swoole 到8.2php
brew install swoole@8.2

问题

安装swoole时后面带的标签是指定安装的相关 php 版本号，无法指定 swoole 版本号，作者相关说明 https://github.com/shivammathur/homebrew-extensions/issues/4225

There is no specific support to install a specific version for an extension in this tap. Please use PECL directly for this purpose.

安装的版本是跟随shivammathur/extensions库的更新 指定 swoole 版本号，文件在Formula/swoole@8.2.rb

解决方法

我们可以更改自己电脑上的扩展库文件，来达到安装旧版swoole 的目的

首先 查看扩展这个文件的 commit 历史，找到对应的想要的版本号文件 如 swoole@8.2: update 5.1.6 bottle. 这个 commit 相关文件内容覆盖自己电脑上的文件

自己电脑上文件的路径参考：/opt/homebrew/Library/Taps/shivammathur/homebrew-extensions/Formula/swoole@8.2.rb

cp /opt/homebrew/Library/Taps/shivammathur/homebrew-extensions/Formula/swoole@8.2.rb /opt/homebrew/Library/Taps/shivammathur/homebrew-extensions/Formula/swoole@8.2.rb.bak

rm /opt/homebrew/Library/Taps/shivammathur/homebrew-extensions/Formula/swoole@8.2.rb

vim /opt/homebrew/Library/Taps/shivammathur/homebrew-extensions/Formula/swoole@8.2.rb

为此写了一个小脚本

#!/usr/bin/env php
<?php

declare(strict_types=1);

$config = [

        '5.1.6' => 'https://raw.githubusercontent.com/shivammathur/homebrew-extensions/54f07aec8e5df40d75786509b7b0cf119dc2eaf7/Formula/swoole%408.1.rb',
