聊聊brew link更换php版本失败问题 本文给大家聊聊brew link更换php版本失败问题，希望对需要的朋友有所帮助！

问题描述：

我透過 brew 安裝三種php版本

php 5.6
php 7.4
php 8.0

$ php -v

PHP 8.0.3 (cli) (built: Mar  4 2021 20:45:17) ( NTS )
Copyright (c) The PHP Group
Zend Engine v4.0.3, Copyright (c) Zend Technologies
    with Zend OPcache v8.0.3, Copyright (c), by Zend Technologies

停用8.0使用7.4

$ brew unlink [email protected] && brew link [email protected]
Unlinking /usr/local/Cellar/php/8.0.3... 0 symlinks removed.
Linking /usr/local/Cellar/[email protected]/7.4.16... 264 symlinks created.
$ php -v

還是一樣版本

我開新的終端機也是一樣8.0.3

PHP 8.0.3 (cli) (built: Mar  4 2021 20:45:17) ( NTS )
Copyright (c) The PHP Group
Zend Engine v4.0.3, Copyright (c) Zend Technologies
    with Zend OPcache v8.0.3, Copyright (c), by Zend Technologies

中規中矩 *** 作了

這是哪裏有少設置了？

分析解决：

你可以尝试安装一个PHP选择器

brew update
brew upgrade

参考文档

https://github.com/shivammathur/homebrew-php

安装指定php brew install shivammathur/php/[email protected]

链接php版本 brew link --overwrite --force [email protected]

如果出现报错

Warning: Already linked: <Cellar Path>
To relink:
  brew unlink <formula> && brew link <formula>

执行

brew unlink [email protected]
brew link --overwrite --force [email protected]

重启服务

apache brew services restart httpd
nginx brew services restart nginx

安装结果

To enable PHP in Apache add the following to httpd.conf and restart Apache:
    LoadModule php7_module /usr/local/opt/[email protected]/lib/httpd/modules/libphp7.so
    <FilesMatch \.php$>
        SetHandler application/x-httpd-php
    </FilesMatch>
Finally, check DirectoryIndex includes index.php
    DirectoryIndex index.php index.html
The php.ini and php-fpm.ini file can be found in:
    /usr/local/etc/php/7.0/
[email protected] is keg-only, which means it was not symlinked into /usr/local,
because this is an alternate version of another formula.
If you need to have [email protected] first in your PATH run:
  echo 'export PATH="/usr/local/opt/[email protected]/bin:$PATH"' >> ~/.zshrc
  echo 'export PATH="/usr/local/opt/[email protected]/sbin:$PATH"' >> ~/.zshrc
For compilers to find [email protected] you may need to set:
  export LDFLAGS="-L/usr/local/opt/[email protected]/lib"
  export CPPFLAGS="-I/usr/local/opt/[email protected]/include"
To have launchd start shivammathur/php/[email protected] now and restart at login:
  brew services start shivammathur/php/[email protected]
Or, if you don't want/need a background service you can just run:
  php-fpm
