Laravel 迁移时报错？

php artisan migrate

In Migrator.php line 418:

  Class 'CreateHouseCostTypesTable' not found

然后运行了 composer dump-autoload

composer dump-autoload
Generating optimized autoload files
> Illuminate\Foundation\ComposerScripts::postAutoloadDump
> @php artisan package:discover
Discovered Package: fideloper/proxy
Discovered Package: laravel/tinker
Discovered Package: nesbot/carbon
Discovered Package: tymon/jwt-auth
Package manifest generated successfully.

再次运行迁移命令

php artisan migrate

In Migrator.php line 418:

  Class 'CreateHouseCostTypesTable' not found

整体为

Mr.Ma@DESKTOP-UL4MB7G MINGW64 /e/czh/data/api (master)
$ php artisan migrate

In Migrator.php line 418:

  Class 'CreateHouseCostTypesTable' not found
