composer not installing laravel project because of the mbstring – CentOS

i am trying to install laravel project by composer install but in return it gives the following error. 

Problem 1
    - Installation request for laravel/framework v7.14.1 -> satisfiable by laravel/framework[v7.14.1].
    - laravel/framework v7.14.1 requires ext-mbstring * -> the requested PHP extension mbstring is missing from your system.
  Problem 2
    - Installation request for league/commonmark 1.4.3 -> satisfiable by league/commonmark[1.4.3].
    - league/commonmark 1.4.3 requires ext-mbstring * -> the requested PHP extension mbstring is missing from your system.
  Problem 3
    - Installation request for facade/ignition 2.0.6 -> satisfiable by facade/ignition[2.0.6].
    - facade/ignition 2.0.6 requires ext-mbstring * -> the requested PHP extension mbstring is missing from your system.
  Problem 4
    - Installation request for mockery/mockery 1.4.0 -> satisfiable by mockery/mockery[1.4.0].
    - mockery/mockery 1.4.0 requires php ^7.3.0 -> your PHP version (7.2.24) does not satisfy that requirement.
  Problem 5
    - Installation request for phpunit/phpunit 8.5.5 -> satisfiable by phpunit/phpunit[8.5.5].
    - phpunit/phpunit 8.5.5 requires ext-mbstring * -> the requested PHP extension mbstring is missing from your system.
  Problem 6
    - Installation request for scrivo/highlight.php v9.18.1.1 -> satisfiable by scrivo/highlight.php[v9.18.1.1].
    - scrivo/highlight.php v9.18.1.1 requires ext-mbstring * -> the requested PHP extension mbstring is missing from your system.
  Problem 7
    - laravel/framework v7.14.1 requires ext-mbstring * -> the requested PHP extension mbstring is missing from your system.
    - facade/flare-client-php 1.3.2 requires illuminate/pipeline ^5.5|^6.0|^7.0 -> satisfiable by laravel/framework[v7.14.1].
    - Installation request for facade/flare-client-php 1.3.2 -> satisfiable by facade/flare-client-php[1.3.2].

But mbstring is already installed in php72. First I check the version of the php --v and it returned

PHP 7.2.24

then checked the loaded modules php72 -m and there was mbstring no problem there too… After that I checked the mbstring is enabled or not php72 -i | grep mbstring and it’s enabled

Multibyte decoding support using mbstring => enabled

In the end why composer is not seeing the mbstring? I check the modules of composer show -p seeing. And NO there is no mbstring! Any idea why composer not seeing the mbstring and how can I fix this issue?

Additionally I am in Centos 7

    Your mbstring extension is missing for php7.2

    Run sudo apt-get install -y php7.2-mbstring

    Edit

    Also, mockery/mockery 1.4.0 requires php ^7.3.0.
    I suggest upgrading your project php version.
