请问有人遇到过这种问题，我正在安装新的laravel 8，希望与其一起安装[jet-stream和livewire] [1]，我使用以下cmd安装了laravel 8：
composer create-project --prefer-dist laravel/laravel blog
然后继续使用...安装喷射流
$ composer require laravel/jetstream
此cmd结果：
无法下载“ http://repo.packagist.org/p/provider-2019%2427b76b9f0218e7440cf8a7d3dfe11f6ac69610e72f5277d4ee2bf31e24c43772.json”文件：php_network_getaddresses：getaddrinfo失败：未知此类主机。 无法打开流：php_network_getaddresses：getaddrinfo失败：此类主机未知。 http://repo.packagist.org无法完全加载，软件包信息是从本地缓存加载的，可能已过期

我尝试通过cm为一个作曲家更新我的PHP版本 ：
$ composer config platform.php 7.4.3
并尝试运行
$ composer require laravel/jetstream
然后结果：

请问这个问题看起来很明显，我需要升级PHP版本，但是我不知道要去哪里
请指导，谢谢 [1]：https://jetstream.laravel.com/

在我看来，信息缺乏。 但... 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) 版权所有 (c) PHP Group Zend Engine v3.4.0, 版权所有 (c) Zend Technologies 使用 Zend OPcache v7.4.19，版权所有 (c)，由 Zend Technologies 提供
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 Composer
现在。 我使用喷射流
laravel new minimarket --git -f --jet
对于这种方法，请安装干净的 laravel 8，我使用 Fedora 34 和 maria 数据库
答案 1 :(得分：-1)
嗨，请检查Laravel 8是否需要php 7.3或更高版本（您正在 问题，因为您使用的是php7.2）
