问题
So apparently now I get this weird error when I want to migrate my database
{"error":{"type":"Symfony\\Component\\Debug\\Exception\\FatalErrorException","message":"Class '' not found","file":"C:\\xampp\\htdocs\\l4crm\\vendor\\laravel\\framework\\src\\Illuminate\\Database\\Migrations\\Migrator.php","line":301}}[Finished in 1.3s]
Everything used to work of course and it doesn't matter which files I try to migrate (I tried only migrating one table, then another, they all give the same error)
Any ideas? I have been staring myself blind at this for over an hour now.
Also "composer dump-autoload" does not do the trick.
My composer.json autoloads the migrations also.

I had the same problem, I searched the internet and I found this solution that you should update your auto-generated classmap (aka autoload) with this composer command:
php composer.phar update
or
composer update
check this link : I found the solution here

I appear to have solved the problem.
For easiness sake to determine the order of migrations I had renamed the migration files to something like
1_create_users_table.php
2_create_..._table.php
3_create_..._table.php
and so on. Apparently this gave me the error, it really had to stay in the "yyyy_mm_dd_hhmmss_create_xxx_table.php" format.
回答3:
if composer dump-autoload doesn't work, check your class name in the migration file. The className should be the same than the file name without the date
回答4:
I had the same problem.
For me, composer update doesn't work (in other situations as well) with Windows for weird reasons.
But,
composer dump-autoload
works.
回答5:
In my case, i had deleted a migration in source files but i didn't on "migrations" table on the database.
Delete the row and refresh migrations and do a "composer dump-autoload -o"
