我已经在 localhost 中创建了数据库

Illuminate\Database\QueryException  : SQLSTATE[HY000] [1045] Access denied for user 'root'@'localhost' (using password: YES
(SQL: select * from information_schema.tables where table_schema = laravel5 and table_name = migrations)

at F:\full stack\laravel\laravel5\vendor\laravel\framework\src\Illuminate\Database\Connection.php: 664
660:         // If an exception occurs when attempting to run a query, we'll format the error
661:         // message to include the bindings with SQL, which will make this exception a
662:         // lot more helpful to the developer instead of just the database's errors.
663:         catch (Exception $e) {
664:             throw new QueryException(
665:                 $query, $this->prepareBindings($bindings), $e
666:             );
667:         }
668:
669:         return $result;

异常跟踪：

更新你的.env文件

标签： php mysql laravel web laravel-5

【解决方案1】：

检查您数据库中'root'@'localhost' 的用户权限。您可能需要为root@localhost 创建一个条目或使用root@127.0.0.1

要创建新用户/补充现有用户，请运行以下命令：

// change your_db_user to root or the user name you specify
// change login_from to 127.0.0.1 or any valid hostname/ip address
// change your_db_password to the password you set in your .env file

$ mysql -u root -p
$ create user your_db_user (skip this step if you're adding a new entry for root or a user that already exists)
$ grant all on your_db_name.* to 'your_db_user'@'login_from' identified by 'your_db_password';
$ flush privileges

能否请您详细说明如何创建条目？

【解决方案2】：

要修复错误，请转到app/Providers/AppServiceProvider.php 并添加启动功能，如下所示。

（确保从 Illuminate\Support\Facades\Schema 导入 Schema 外观。

<?php

namespace App\Providers;

use Illuminate\Support\ServiceProvider;
use Illuminate\Support\Facades\Schema;


public function boot()
{
    Schema::defaultStringLength(191);
}
