我嘗試通過 cm 為 Composer 更新我的 PHP 版本：

$ composer config platform.php 7.4.3

並嘗試運行

$ composer require laravel/jetstream

這然后結果：

請問題似乎很直觀，我需要升級我的 PHP 版本，但我不知道在哪里

請指導，謝謝[1]： https : //jetstream.laravel.com/

Answer 1

在我看來，信息缺乏。 但是……就我而言。！

composer global remove laravel / installer
composer global remove laravel / laravel **

和

composer global require laravel / installer

php -v

PHP 7.4.19 (cli) (built: May 4 2021 11:06:37) (NTS) 版權所有 (c) The PHP Group Zend Engine v3.4.0, 版權所有 (c) Zend Technologies with Zend OPcache v7.4.19, 版權所有 ( c)，由 Zend Technologies

在那里你可以使用`

composer global config platform.php 7.4.19

使用您的 php 版本全局配置作曲家

現在。 我使用噴射流

laravel new minimarket --git -f --jet

對於這種方法，請安裝干凈的 laravel 8，我使用 Fedora 34 和 maria 數據庫

Answer 2

請檢查 Laravel 8 是否需要 PHP 7.3 或更高版本（您遇到問題，因為您使用的是 php7.2 ）

請檢查文檔https://laravel.com/docs/8.x
