求大神指点，PHP artisan migrate 执行报错：check the manual tha t corresponds to your MySQL server version for the right syntax to use near 'layouts character set utf8mb4 collate utf8mb4_unicode_ci'？

php artisan migrate执行错误结果为：
SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual tha
t corresponds to your MySQL server version for the right syntax to use near 'layouts character set utf8mb4 collate
utf8mb4_unicode_ci' at line 1 (SQL: create table migrations (id int unsigned not null auto_increment primary
key, migration varchar(191) not null, batch int not null) layouts character set utf8mb4 collate utf8mb4_unicod
e_ci)
In Connection.php line 452:

这里的sql里为什么会多一个layouts？
