Today When using a third-party package laravel-admin, an error like this occurred: SQLSTATE[42000]: Syntax error or access violation: 1103 Incorrect table name ''.

Clear the configuration file cache

vagrant@homestead:~/Code/laravel-shop$ php artisan config:cache

Execute the publish command again, and it will be fine:

vagrant@homestead:~/Code/laravel-shop$ php artisan admin:install
