I have installed symfony 3.3 using below mention composer code.
composer create-project symfony/framework-standard-edition my_project_name 3.3
Now i would like to install knp-paginator-bundle , using ' composer require knplabs/knp-paginator-bundle ' , but whenever I run this command, can't get past after the message - 'Updating dependencies (including require-dev)'
Could someone guide me how to install them?
