Script Illuminate\Foundation\ComposerScripts::postAutoloadDump handling the post-autoload-dump event terminated with an exception

Hello, I am new to Laravel.

I am trying to install composer with command composer install but I have been having this error with composer dump-autoload also.

I am unable to install any packages. Following suggestions on stackoverflow, I even updated composer by running composer global update. I have no clue what's happening. Please help.

composer install
