[UmerDaraz163]

I run command composer require arrilot/laravel-widegts
but on updating dependencies killed.
run successfully on my local environment but killed on live server.
"Warning from https://repo.packagist.org: You are using an outdated version of Composer. Composer 2.0 is now available and you should upgrade. See https://getcomposer.org/2
Updating dependencies (including require-dev)
Killed"
How can I solve this?
