迁移数据库报错

php artisan migrate

E:\wamp\www\log>php artisan migrate
Migration table created successfully.


  [Illuminate\Database\QueryException]
  SQLSTATE[42000]: Syntax error or access violation: 1071 Specified key was too long; max key length is 1000 bytes (SQL: alter table `users` add unique `users_email_unique`(`email`))



  [PDOException]
  SQLSTATE[42000]: Syntax error or access violation: 1071 Specified key was too long; max key length is 1000 bytes

编码和laravel框架 里的数据库配置一样，数据库版本是5.7.14，迁移过去两张表，但是重置密码的表没有导进去，求解
