我正在使用 Laravel 5 并遇到以下异常：

我的数据库配置文件是：

将.env文件放在根目录中并将此代码粘贴到那里。

APP_ENV=local
APP_DEBUG=true
APP_KEY=1CaND3OKKvOGSBAlCg6IyrRmTQWwZjOO

DB_HOST = localhost
DB_DATABASE = YOUR_DATABASE_NAME
DB_USERNAME = USER_NAME
DB_PASSWORD = PASSWORD

CACHE_DRIVER=file
SESSION_DRIVER=file
QUEUE_DRIVER=sync

MAIL_DRIVER=smtp
MAIL_HOST=mailtrap.io
MAIL_PORT=2525
MAIL_USERNAME=null
MAIL_PASSWORD=null

在此处更新您的数据库、用户名和密码字段，它应该可以解决您的问题。在您的配置文件env()中，函数正在从此处查找此文件和变量。

更新：您必须在运行应用程序或迁移之前创建一个空白数据库。

如果在 XAMPP 中安装 MySQL 时没有默认用户名，则应DB_USERNAME=设置为。root

我们忘记DB_USERNAME=在.env文件中设置，所以我们得到了这个错误：

SQLSTATE[HY000] [1044] 拒绝用户“@”localhost”访问数据库“forge”

打开.env文件并进行编辑。只需设置正确的数据库凭据：

DB_USERNAME=         //Your Database Username

DB_USERNAMEroot如果您在安装时没有默认用户名，则应设置为

更改.env后，在终端中输入此命令以清除缓存：php artisan config:cache

注意：如果仍然有错误

如果您使用的是 PHP 的默认 Web 服务器（例如php artisan serve），您需要重新启动服务器

或者

如果您使用过XAMPP，请重新启动您的Apache服务器

在未来的某个时候。如果使用 MySQL 而不是 Homestead，这将是一个基本设置。配置->database.php 文件

'mysql' => [
        'driver'    => 'mysql',
        'host'      => env('DB_HOST', 'localhost'),
        'database'  => env('DB_DATABASE', 'yourDatabaseName'),
        'username'  => env('DB_USERNAME', 'root'),
        'password'  => env('DB_PASSWORD'),
        'charset'   => 'utf8',
        'collation' => 'utf8_unicode_ci',
        'prefix'    => '',
        'strict'    => false,
    ],

在你的 .env 文件中

APP_ENV=local
APP_DEBUG=true
APP_KEY=ruA9CAKRJCFgLOD1nc5o1BmvaTGokasi

DB_HOST=localhost
DB_DATABASE=yourDatabaseName


CACHE_DRIVER=file
SESSION_DRIVER=file
QUEUE_DRIVER=sync

MAIL_DRIVER=smtp
MAIL_HOST=mailtrap.io
MAIL_PORT=2525
MAIL_USERNAME=null
MAIL_PASSWORD=null
MAIL_ENCRYPTION=null

如果您运行该命令，它应该可以顺利运行。

更改帐户所有权后遇到了同样的问题，所以我最终做了以下事情：

（这对我有用）

记下您的实际用户和密码 转到您的 cPanel（即如果您使用的是 cPanel） 从 Databases 选项卡中，选择 MySQL Databases。导航到当前用户删除与您有冲突的数据库对应的用户。删除后，转到将用户添加到数据库选项卡并重新输入用户名和密码，这将使用当前所有者权限重新生成连接。

您可以通过以下方式检查当前环境： php artisan env

下一个

  • 在配置/开发下创建 | 暂存（文件夹）
  • 保存一个database.php 文件development | staging access
  • 编辑.env 文件 APP_ENV=development | staging | production

此问题可能是由文件没有预期的“.env”扩展名引起的。

如果您在 Windows 中隐藏了文件扩展名（默认情况下启用），那么它很容易看起来像扩展名是“.env”，而实际上它类似于“.env.txt”。

这意味着程序将无法找到您的“.env”文件，因为它没有正确的扩展名。

使用 Sublime Text 之类的编辑器打开文件，您会看到实际的扩展名是什么。如果它具有“.txt”扩展名，请删除该部分并重新保存。

我收到了相同的消息，但用户名为空。用户名始终为空。

问题出在 MySQL 上。SQLSTATE 错误消息直接从 MySQL 传递。

所以我删除了数据库和用户。在 PhpMyAdmin 的 Databases 选项卡中重新创建了数据库。重要的是分别添加了用户和权限。这解决了这个问题。

我可以从 MySQL 客户端连接并运行迁移。

当您在同一项目/查询中使用多个数据库时，也会出现此问题

我通过对所有数据库使用相同的 DB_USERNAME 解决了同样的问题，因为我在同一个项目中使用了多个数据库，并且每个数据库 DB_USERNAME 都不同，所以当我从多个数据库运行查询选择、更新、删除等时，就会得到这个错误。

因为如果您在查询中使用多个表并且数据库 DB_USERNAME 不同，您将收到此错误。

解决方案：

如果您使用/连接多个数据库，那么您应该对所有数据库使用相同的 DB_USERNAME

如果您在访问数据库时不需要登录

尝试数据库用户名和root密码字段留空

这解决了我的问题
