在 Homestead v13.2.1 中切换 PHP 版本(仅限某个项目)

由永夜 · 2022/09/01

1、在 Homestead 中执行 composer update 报错：Your requirements could not be resolved to an installable set of packages.。原因在于 PHP 版本为 8.0 ，而软件包的版本依赖于 7。如图1

图1

vagrant@homestead:~/Code/laravel-8-shop$ composer update
Loading composer repositories with package information
Updating dependencies
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Root composer.json requires laravel/nova ^3.14 -> satisfiable by laravel/nova[v3.14.0].
    - laravel/nova v3.14.0 requires php ^7.2.5 -> your php version (8.0.1) does not satisfy that requirement.
  Problem 2
    - Root composer.json requires laravel/ui 3.0 -> satisfiable by laravel/ui[v3.0.0].
    - laravel/ui v3.0.0 requires php ^7.3 -> your php version (8.0.1) does not satisfy that requirement.

2、参考：https://learnku.com/docs/laravel/5.8/homestead/3882#multiple-php-versions 。Homestead 6 在同一个虚拟机上引入了对多个 PHP 版本的支持。你可以在你的 Homestead.yaml 文件中指定要用于给定站点的 PHP 版本。

sites:
    - map: laravel-8-shop-homestead.test
      to: /home/vagrant/Code/laravel-8-shop/public
      php: "7.4"

3、退出 vagrant 后，执行命令：cd ~/Homestead && vagrant provision && vagrant up。

vagrant@homestead:~/Code/laravel-8-shop$ ls /etc/php
5.6  7.0  7.1  7.2  7.3  7.4  8.0

4、重新进入后，发现共享文件夹竟然为空。如图2

5、决定还原第二步骤所做的更改。仍然为空。怀疑与开启 NFS 有关系，决定去掉：type: “nfs”。

folders:
    - map: E:/wwwroot/vagrant
      to: /home/vagrant/Code
      type: "nfs"

6、重启并应用虚拟机，执行命令：vagrant reload –provision

7、查看当前的 PHP 版本，默认为 8.0，那么 composer 执行使用仍然会使用 8.0，下载 composer.phar。参考：https://getcomposer.org/download/ 。进入项目根目录，复制命令粘贴后回车。如图3

8、执行：php7.4 composer.phar update，不再报错。如图4

10、访问首页，报错，查看 Context，PHP version 为 7.4.14。符合预期。如图5
