I am using magento version 2.3.1
When I have updated composer via command
php composer update
I get this error
Package container-interop/container-interop is abandoned, you should avoid using it. Use psr/container instead.
Package phpunit/phpunit-mock-objects is abandoned, you should avoid using it. No replacement was suggested.
please anyone guide me how to solve this error
currently not working any command, giving same error when run command
thanks in advance
