在执行 php artisan migrate出现错误

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

解决方案

1. 修改config/database.php文件，将utf8mb4替换成utf8
2. 修改app/Providers/AppServiceProvider.php文件

public function boot()
{
    \Illuminate\\Support\\Facades\\Schema::defaultStringLength();
}
