Having issues after upgrading to laravel 12

@Merklin

 $requireFile = \Closure::bind(static function ($fileIdentifier, $file) {
            if (empty($GLOBALS['__composer_autoload_files'][$fileIdentifier])) {
                $GLOBALS['__composer_autoload_files'][$fileIdentifier] = true;

                require $file;
            }

Here's how the autoload_real.php file referenced by the error looks like, I'd appreciate it if you have any ideas on how to solve the issue

<?php

// autoload_real.php @generated by Composer

class ComposerAutoloaderInitecee385275a32a93bf8d0d688f5cbd04
{
    private static $loader;

    public static function loadClassLoader($class)
    {
        if ('Composer\Autoload\ClassLoader' === $class) {
            require __DIR__ . '/ClassLoader.php';
        }
    }

    /**
     * @return \Composer\Autoload\ClassLoader
     */
    public static function getLoader()
    {
        if (null !== self::$loader) {
            return self::$loader;
        }

        spl_autoload_register(array('ComposerAutoloaderInitecee385275a32a93bf8d0d688f5cbd04', 'loadClassLoader'), true, true);
        self::$loader = $loader = new \Composer\Autoload\ClassLoader(\dirname(__DIR__));
        spl_autoload_unregister(array('ComposerAutoloaderInitecee385275a32a93bf8d0d688f5cbd04', 'loadClassLoader'));

        require __DIR__ . '/autoload_static.php';
        call_user_func(\Composer\Autoload\ComposerStaticInitecee385275a32a93bf8d0d688f5cbd04::getInitializer($loader));

        $loader->register(true);

        $filesToLoad = \Composer\Autoload\ComposerStaticInitecee385275a32a93bf8d0d688f5cbd04::$files;
        $requireFile = \Closure::bind(static function ($fileIdentifier, $file) {
            if (empty($GLOBALS['__composer_autoload_files'][$fileIdentifier])) {
                $GLOBALS['__composer_autoload_files'][$fileIdentifier] = true;

                require $file;
            }
        }, null, null);
        foreach ($filesToLoad as $fileIdentifier => $file) {
            $requireFile($fileIdentifier, $file);
        }

        return $loader;
    }
}

@jlrdw yes I did, updated dependencies at composer.json and Laravel Installer as per the guide.

@Dosmukhanbet what is:

/Users/dos/Desktop/code/ship/

@jlrdw path to my app folder

@Dosmukhanbet I never seen a path like that, but try deleting the vendor folder, update composer to latest version:

composer self-update

then

composer clear-cache

then rename the composer.lock file

then try to run

composer install

again.

Also double check you didn't miss anything in the upgrade guide:

https://laravel.com/docs/12.x/upgrade

@kggeorgiev You are right, the src folder in the /vendor/laravel/framework/ directory is missing at all. Can you please advise me how I can reinstall laravel 12 if running any composer command returns an error?

@maxxd it won’t work, if I run any command it returns error

@Dosmukhanbet reinstall composer and make sure you set the php folder.
