I'm trying to upgrade Magento 2.4.0 to 2.4.5, i didn't upgrade PHP version, i'm using 7.4

composer require magento/product-community-edition 2.4.5 --no-update

I got this message

The "magento/inventory-composer-installer" plugin was skipped because it requires a Plugin API version ("^1.1") 
that does not match your Composer installation ("2.3.0"). You may need to run composer update with 
the "--no-plugins" option.
The "laminas/laminas-dependency-plugin" plugin was skipped because it requires a Plugin API version ("^1.1") 
that does not match your Composer installation ("2.3.0"). 
You may need to run composer update with the "--no-plugins" option.


composer update --ignore-platform-reqs

Problem 1
- Root composer.json requires magento/product-community-edition 2.4.5 -> satisfiable by magento/product-community-edition[2.4.5].
- magento/product-community-edition 2.4.5 requires guzzlehttp/guzzle ^7.4.2 -> found guzzlehttp/guzzle[7.4.2, ..., 7.5.0] but itconflicts with your root composer.json require (^6.5).

Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.

Should i update composer.json manually?

  • Can you try to copy the composer.json content from 2.4.5 to 2.4.0 then run composer update Commented Sep 2, 2022 at 15:54
  • i have upgraded module composer composer require magento/composer-root-update-plugin ~2.0 --no-update then i found in doc "Adobe Commerce 2.4.2 introduced support for Composer 2. If you are attempting to upgrade from <2.4.1, you must first upgrade to a version that is compatible with Composer 2 (for example, 2.4.2) using Composer 1 before upgrading to Composer 2 for >2.4.2 upgrades" Commented Sep 2, 2022 at 17:40

To upgrade Magento 2.4.0 to 2.4.5, you first need to upgrade the PHP version to 8.1 to avoid conflict and dependency issues.

What you can do is:

  • Enable the maintenance mode: php bin/magento maintenance:enable

  • Back up your application and composer:

    cp composer.json composer.json.bak

Note: It is better to perform on the development store.

  • Upgrade the composer version to 2 latest version, Since Adobe Commerce requires to be in latest version of composer. Run the command: composer require-commerce magento/<product> <version> --no-update [--interactive-root-conflicts] [--force-root-updates] [--help]

  • Upgrade and install: composer require-commerce magento/product-community-edition 2.4.5 --no-update

  • Run composer update

  • Run setup upgrade to upgrade database and compile

  • Disable maintenance mode.

sudo find . -type d -exec chmod 775 {} \;

It looks like you are running into some dependency issues when trying to upgrade Magento 2.4.0 to 2.4.5 without upgrading PHP.

Here's how you can try to upgrade to 2.4.0 to 2.4.5:

  1. Upgrade to PHP version. Magento 2.4.5 requires at least PHP 7.4.25, so this would be the recommended approach. You would need to make sure your extensions and code are compatible before upgrading PHP.

  2. Manually update your root composer.json file to require Guzzle ^7.4. This will allow the upgrade to proceed but could potentially cause issues if you have other dependencies relying on Guzzle 6.x.

  3. Use the --with-all-dependencies (-W) flag to force Composer to allow the upgrade. This may cause unnecessary upgrades/downgrades of other packages though.

Overall, I would recommend upgrading your PHP version if possible. If not, be very careful in managing your dependencies and test everything thoroughly if forcing the upgrade.
