Question

I am working on an upgrade project from Magento 2.3.2.p2 EE to 2.4.4 EE.

After the composer update was done successfully I found the below error while run php bin/magento commands, can anyone help me on the same.

I have already run this composer dumpautoload but not still not working.

$ php bin/magento PHP Warning: require(/home/../vendor/composer/../magento/project-enterprise-edition/app/etc/NonComposerComponentRegistration.php): Failed to open stream: No such file or directory in /home/../vendor/composer/autoload_real.php on line 57 PHP Fatal error: Uncaught Error: Failed opening required '/home/../vendor/composer/../magento/project-enterprise-edition/app/etc/NonComposerComponentRegistration.php' (include_path='/home/../vendor/magento/zendframework1/library:.:/usr/share/php') in /home/../vendor/composer/autoload_real.php:57 Stack trace: #0 /home/../vendor/composer/autoload_real.php(40): composerRequiredb672302d8264da3ebc40879939070dd() #1 /home/../vendor/autoload.php(25): ComposerAutoloaderInitdb672302d8264da3ebc40879939070dd::getLoader() #2 /home/../app/autoload.php(51): include('...') #3 /home/../app/bootstrap.php(43): require_once('...') #4 /home/../bin/magento(14): require('...') #5 {main} thrown in /home/../vendor/composer/autoload_real.php on line 57

Answer 1

1. app/etc/NonComposerComponentRegistration.php permissions should be set to 666.

2. If a setting is missing from your composer.json file, some directories will not copy from the Adobe Commerce Code Base. The package and the update/patch can’t apply because files will not be found.

Please change your extra section to match that provided below.

"extra":{
  "magento-force": true,
  "magento-deploystrategy": "copy"
}

And re-attempt deployment

rm -rf vendor
composer install
bin/magento setup:upgrade
bin/magento setup:di:compile

For other, who has below issue (the file path does not the same as the Original Poster):
Warning: require(/var/www/html/app/etc/NonComposerComponentRegistration.php): failed to open stream: No such file or directory, do the following steps to resolve that issue:

1. Remove the vendor directory and clear the composer cache:

rm -rf vendor
composer clear-cache

2. Run the following commands:

composer install
bin/magento setup:upgrade
bin/magento setup:di:compile
