Meaning

Anonymous components live in resources/views/components/alert.blade.php; class components in app/View/Components/Alert.php with a view. Sub-folders use dots (<x-forms.input />). Check names, case, and for packages that the service provider registers components.

Common causes

  • Missing resources/views/components/alert.blade.php
  • Wrong sub-folder/dot notation
  • Case mismatch on Linux
  • Package component not registered/published
  • Cached views stale

⚡ Quick fix

  1. Create resources/views/components/alert.blade.php or the class
  2. Use dot notation for folders
  3. php artisan view:clear

Detailed fix by platform

Laravel

  1. php artisan make:component Alert (class + view) or php artisan make:component Alert --view (anonymous)

How to diagnose

  1. File — Component view exists?
  2. Name — Dots for folders?
  3. Package — Published?
