Your requirements could not be resolved to an installable set of packages.
Problem 1 - Root composer.json requires magento/product-community-edition 2.4.3 -> satisfiable by magento/product-community-edition[2.4.3]. - magento/product-community-edition 2.4.3 requires php ~7.3.0||~7.4.0 -> your php version (7.2.34) does not satisfy that requirement. Problem 2 - Root composer.json requires dealerdirect/phpcodesniffer-composer-installer ^0.5.0 -> satisfiable by dealerdirect/phpcodesniffer-composer-installer[v0.5.0]. - dealerdirect/phpcodesniffer-composer-installer v0.5.0 requires composer-plugin-api ^1.0 -> found composer-plugin-api[2.2.0] but it does not match the constraint.
what is the reason?
See if you're really using php 7.4 by typing php -v
in the terminal. When you are sure that your php version is correct, delete the composer. lock file ( make a backup beforehand ). Try updating with the command:
composer require magento/product-community-edition:2.4.5 -W
If that doesn't work, post the contents of the composer. json file
If you are migrating from 2.3.4 to 2.4.3, you need to make the following and please follow these below steps:
1: Backup composer.json: Run the command
cp composer.json composer.json.bak
2: Upgrade your Magento: Run the commmand
composer require-commerce magento/<product> <version> --no-update [--interactive-root-conflicts] [--force-root-updates] [--help]
3: Update the dependecies:
composer update
For example, Specify the metapackage:
Magento Open Source: composer require-commerce magento/product-community-edition 2.4.4 --no-update
Adobe Commerce: composer require-commerce magento/product-enterprise-edition 2.4.4 --no-update
4: Composer Update: Run composer update
5: Update the database schema and data. bin/magento setup:upgrade
6: Disable Magento maintenance mode. bin/magento maintenance:disable
7: Restart Varnish. (Optional) Restart Varnish If you use it for page caching: service varnish restart
Please switch to PHP 7.4 first then check perform the upgrade.
