Facing issue in installing phpMemAdmin while running composer install

[Asrivast1]

I was installing phpMemAdmin through compose install and after adding the following configuration in the composer.json as described in the documentation:

 `{
    "require": {
        "clickalicious/phpmemadmin": "~0.3"
    },
    "scripts": {
    	"post-autoload-dump": [
        	"Clickalicious\\PhpMemAdmin\\Installer::postInstall"
    	]
    }
}`

But post this step when we run the compose install, I am getting the following error in the git bash.

  [TypeError]
