Hello,
The issue appears because, when you are installing the module using the composer, you should also define from which php the composer should run. This case arrises when different php are installed.
Check the php which you are using by command :

which php
php -v

After that mention the php path before the composer like :

/opt/lampp/bin/php composer require vendor/module-name

OR

/vendor/composer/composer/bin/composer require vendor/module-name
