Mari kita bincangkan tentang kegagalan pautan brew untuk menukar versi php

Artikel ini akan bercakap tentang kegagalan pautan brew untuk menukar versi php Saya harap ia akan membantu rakan-rakan yang memerlukan!

Penerangan masalah:

Saya memasang tiga versi php melalui brew

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

Lumpuhkan 8.0 dan gunakan 7.4

$ brew unlink php@8.0 && brew link php@7.4
Unlinking /usr/local/Cellar/php/8.0.3... 0 symlinks removed.
Linking /usr/local/Cellar/php@7.4/7.4.16... 264 symlinks created.
$ php -v

Ia masih versi yang sama

Saya membuka terminal baharu dan ia adalah 8.0.3 yang sama

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

Ia berfungsi dengan baik

Di manakah tetapan yang hilang?

Analisis dan penyelesaian:

Anda boleh cuba memasang pemilih PHP

brew update
brew upgrade

Rujuk dokumentasi

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

Pemasangan Tentukan php brew install shivammathur/php/php@7.3

pautan versi php brew link --overwrite --force php@7.3

Jika ralat berlaku

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

laksanakan

brew unlink php@7.3
brew link --overwrite --force php@7.3

Mulakan semula perkhidmatan

apache brew services restart httpd
nginx brew services restart nginx

Hasil pemasangan

To enable PHP in Apache add the following to httpd.conf and restart Apache:
    LoadModule php7_module /usr/local/opt/php@7.0/lib/httpd/modules/libphp7.so
    <FilesMatch \.php$>
        SetHandler application/x-httpd-php
    </FilesMatch>
Finally, check DirectoryIndex includes index.php
    DirectoryIndex index.php index.html
The php.ini and php-fpm.ini file can be found in:
    /usr/local/etc/php/7.0/
php@7.0 is keg-only, which means it was not symlinked into /usr/local,
because this is an alternate version of another formula.
If you need to have php@7.0 first in your PATH run:
  echo &#39;export PATH="/usr/local/opt/php@7.0/bin:$PATH"&#39; >> ~/.zshrc
  echo &#39;export PATH="/usr/local/opt/php@7.0/sbin:$PATH"&#39; >> ~/.zshrc
For compilers to find php@7.0 you may need to set:
  export LDFLAGS="-L/usr/local/opt/php@7.0/lib"
  export CPPFLAGS="-I/usr/local/opt/php@7.0/include"
To have launchd start shivammathur/php/php@7.0 now and restart at login:
  brew services start shivammathur/php/php@7.0
Or, if you don&#39;t want/need a background service you can just run:
  php-fpm
