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

Hello, I am new to Laravel.

I am trying to install a package using composer require tcg/voyager from the CLI Undefined index: HTTP_HOST exception. 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.

Here is the more detailed log.

composer require tcg/voyager
