@Sheba ,

seems like your composer is using php7.2 

to update that you can use the following command to get a new composer.phar within your webroot 

php -r "readfile('https://getcomposer.org/installer');" | php

now you can use the following command to use composer 

php composer.phar update

kindly Accept as a solution if this works for you and give Kudos.

Hello @Sheba 

Magento 2.4 modules are compatible with PHP 7.4, upgrade your php version and try again.

Hope it helps !

Thanks for your suggestion.  What path on webroot should I be to run command?

[amitsamsukha]

you can run these commands on the Magento root folder
