error on install?

[calamusid]

I can't have cash on delivery module in backend

I use:
composer require msp/cashondelivery

this is the result:
Using version ^1.1 for msp/cashondelivery
./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
Nothing to install or update
Package fabpot/php-cs-fixer is abandoned, you should avoid using it. Use friendsofphp/php-cs-fixer instead.
