I am upgrading Magento version from 2.1.9 to latest i.e. (2.3.3).
Steps I followed are:
composer require magento/product-enterprise-edition 2.3.3 --no-update
composer require --dev allure-framework/allure-phpunit:~1.2.0 friendsofphp/php-cs-fixer:~2.14.0 lusitanian/oauth:~0.8.10 magento/magento-coding-standard:~3.0.0 magento/magento2-functional-testing-framework:2.4.5 pdepend/pdepend:2.5.2 phpmd/phpmd:@stable phpunit/phpunit:~6.5.0 sebastian/phpcpd:~3.0.0 squizlabs/php_codesniffer:~3.4.0 --sort-packages --no-update
3.composer remove --dev sjparkinson/static-review fabpot/php-cs-fixer --no-update
4.composer remove magento/module-bundle-sample-data magento/module-theme-sample-data magento/module-widget-sample-data magento/module-sales-sample-data magento/module-wishlist-sample-data magento/module-catalog-sample-data magento/module-tax-sample-data magento/module-sales-rule-sample-data magento/module-customer-sample-data magento/module-cms-sample-data magento/module-downloadable-sample-data magento/module-review-sample-data magento/module-catalog-rule-sample-data magento/module-msrp-sample-data magento/module-gift-card-sample-data magento/module-product-links-sample-data magento/module-configurable-sample-data magento/module-grouped-product-sample-data magento/module-customer-balance-sample-data magento/module-gift-registry-sample-data magento/module-target-rule-sample-data magento/module-multiple-wishlist-sample-data magento/sample-data-media magento/module-offline-shipping-sample-data magento/module-swatches-sample-data --no-update
5.composer update
The issue I am facing is that I am unable to receive any output of composer update command.
Checked log as well and found nothing.
I am unable to proceed further after this:
Loading composer repositories with package information
Updating dependencies (including require-dev)
Any idea why is it so ?
