Is there a way to use Sage 9 with PHP 8.1?

sage

Hi @Clementine_FERNANDEZ,

I upgraded a Sage 9-project just recently to work with PHP 8.1 so I can gladly share what worked for me:

Essentially you’d have to replace the sage-installer and sage-lib packages in the theme’s composer.json to use the forked variants that have been updated to work with PHP 8.x.

This is my composer-file:

{
  "name": "roots/sage",
  "type": "wordpress-theme",
  "license": "MIT",
  "description": "WordPress starter theme with a modern development workflow",
  "homepage": "https://roots.io/sage/",
  "authors": [
    {
      "name": "Ben Word",
      "email": "ben@benword.com",
      "homepage": "https://github.com/retlehs"
    },
    {
      "name": "Scott Walkinshaw",
      "email": "scott.walkinshaw@gmail.com",
      "homepage": "https://github.com/swalkinshaw"
    },
    {
      "name": "QWp6t",
      "email": "hi@qwp6t.me",
      "homepage": "https://github.com/qwp6t"
    }
  ],
  "keywords": ["wordpress"],
  "support": {
    "issues": "https://github.com/roots/sage/issues",
    "forum": "https://discourse.roots.io/"
  },
  "autoload": {
    "psr-4": {
      "App\\": "app/"
    }
  },
  "repositories": [
    { "type": "vcs", "url": "https://github.com/jeh5256/sage-installer" },
    { "type": "vcs", "url": "https://github.com/jeh5256/sage-lib" }
  ],
  "require": {
    "php": "^7.4|^8.0",
    "composer/installers": "^2.0",
    "soberwp/controller": "~2.1.0",
    "roots/sage-installer": "^2.0",
    "roots/sage-lib": "dev-master",
    "log1x/blade-svg-sage": "dev-chore/illuminate-8.x"
  },
  "require-dev": {
    "squizlabs/php_codesniffer": "^2.8.0",
    "filp/whoops": "^2.12"
  },
  "scripts": {
    "test": ["phpcs"],
    "post-create-project-cmd": [
      "Roots\\Sage\\Installer\\ComposerScript::postCreateProject"
    ]
  }
}

Note that I reorder the packages slightly and referenced the log1x/blade-svg-sage which is optional but also needs an update to be compatible, thus listing this as well.

If I remember correctly the illuminate/support-package is listed as a dependency with another package so it can be safely omitted here.

Compare to Sage 9’s default composer.json.

Let me know if that works out for you!
