error creating migration in laravel: 'failed to open stream'

i got this error and i have found a solutions over the community :

php artisan cache:clear

this will delete cached files

composer dump-autoload

composer dump-autoload, will re-generating optimized autoload files for your project agian

php artisan migrate:refresh

then create a new fresh migrate for your database

php artisan make:migration create_users_table --create=users

finally let's start make your new migration file

I get this error on regular basis, here are some things that might help:

php artisan cache:clear

or delete the cache manually in the bootstrap directory (it is responsible for the route and services cache.

also these methods could help:

composer dump-autoload -o
composer update

Composer dump-autoload regenerates the list of all classes that need to be included in the project (autoload_classmap.php).

the -o / --optimize option converts PSR-4/PSR-0 rules into classmap rules, as a result autoloader doesn't need to access the filesystem, making it run faster - which also is often the source of the problem since Laravel autoloader uses this optimization (caching).

also rolling back the migration has helped to solve the problem several times (if the migration was successful):

php artisan migrate:rollback
