CakePHP 3 到 PHP 8.1 - Composer 错误？

Question

我的 CakePHP 3 项目需要更新以支持 PHP 8.1，但我无法让 Composer 更新正常工作。

每当我这样做时，我都会收到这些错误：

  Problem 1
- cakephp/cakephp[3.9.0, ..., 3.9.3] require laminas/laminas-diactoros ^1.4.0 -> satisfiable by laminas/laminas-diactoros[1.4.0, ..., 1.8.7p2].
- cakephp/cakephp[3.8.0, ..., 3.8.13] require zendframework/zend-diactoros ^1.4.0 -> satisfiable by laminas/laminas-diactoros[1.4.0, ..., 1.8.7p2], zendframework/zend-diactoros[1.4.0, ..., 1.8.7].
- zendframework/zend-diactoros[1.4.0, ..., 1.4.1] require php ^5.4 || ^7.0 -> your php version (8.1.10) does not satisfy that requirement.
- laminas/laminas-diactoros[1.4.0, ..., 1.4.1] require php ^5.4 || ^7.0 -> your php version (8.1.10) does not satisfy that requirement.
- zendframework/zend-diactoros[1.5.0, ..., 1.8.7] require php ^5.6 || ^7.0 -> your php version (8.1.10) does not satisfy that requirement.
- laminas/laminas-diactoros[1.5.0, ..., 1.8.7p2] require php ^5.6 || ^7.0 -> your php version (8.1.10) does not satisfy that requirement.
- cakephp/cakephp[3.9.4, ..., 3.10.5] require php >=5.6.0,<8.0.0 -> your php version (8.1.10) does not satisfy that requirement.
- Root composer.json requires cakephp/cakephp ~3.8 -> satisfiable by cakephp/cakephp[3.8.0, ..., 3.10.5].

这是我的作曲家文件：

},

    "cakephp/cakephp-codesniffer": "Allows to check the code against the coding standards used in CakePHP."
},
"autoload": {
    "psr-4": {
        "App\\": "src"
    }
},
"autoload-dev": {
    "psr-4": {
        "App\\Test\\": "tests",
        "Cake\\Test\\": "./vendor/cakephp/cakephp/tests"
    }
},
"scripts": {
    "post-install-cmd": "App\\Console\\Installer::postInstall",
    "post-create-project-cmd": "App\\Console\\Installer::postInstall",
    "post-autoload-dump": "Cake\\Composer\\Installer\\PluginInstaller::postAutoloadDump"
},
"minimum-stability": "stable",
"prefer-stable": true,
"config": {
    "allow-plugins": {
        "cakephp/plugin-installer": true
    }
}

}

我可以毫无问题地执行作曲家安装命令。我也尝试过作曲家更新 --with-all-dependencies 但同样的问题。

有人对我能做些什么来解决这个问题有任何想法吗？ 非常感谢:)

CakePHP 3 不支持 PHP 8。

CakePHP 核心	分行	PHP 分钟	PHP 最大
