Fixing Laravel Valet Error – No Words Barred

Sooooo we needed to jump our local environment from PHP 7.4 to PHP 8.1 in order to work on a different project.

We started by running the command:

Valet use php@8.1

That provided the following error:

Fatal error: Composer detected issues in your platform: Your Composer dependencies require a PHP version ">= 8.1.0". You are running 7.4.27. in /Users/sam/.composer/vendor/composer/platform_check.php on line 25

To fix this issue we ran:

brew link php

This command resulted in:

brew link php
Unlinking /usr/local/Cellar/php@7.4/7.4.27.reinstall... 25 symlinks removed.
Linking /usr/local/Cellar/php/8.1.2.reinstall... 24 symlinks created.

From there we could run “valet use php 8.2” and our new project was happy. This post was also super helpful, it provides solutions for a few other versions oh PHP so if anyone else out there is stuck you can try the link below:
