我该如何解决？

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空白数据库。

将来的某个时间。如果使用MySQL而不是Homestead，这将是一个基本设置。 Config-＆gt; 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,
],
并在.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。

此问题可能是由于文件没有预期的“ .env”扩展名引起的。
如果Windows中隐藏了文件扩展名（默认情况下处于打开状态），则实际上扩展名是“ .env”时，它很容易看起来。 env.txt”。
这意味着该程序将没有正确的扩展名，因此无法找到您的“ .env”文件。
使用Sublime Text之类的编辑器打开文件，您将看到 actual 扩展名是什么。如果扩展名为“ .txt”，请删除该部分并重新保存。

我收到相同的消息，但用户名为空。用户名始终为空。
问题出在MySQL。直接从MySQL传递SQLSTATE错误消息。
因此，我删除了数据库和用户。在PhpMyAdmin的“数据库”选项卡中重新创建数据库。并且重要的是分别添加了用户和特权。这解决了问题。
我可以从MySQL客户端连接并运行迁移。

我们忘记在 .env 文件中设置ems，因此出现此错误：
SQLSTATE [HY000] [1044]用户“ @'localhost”的访问被拒绝 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即可：
DB_USERNAME= DB_USERNAME= //Your Database Username
应设置为DB_USERNAME
更改 .env 后，请在终端中输入以下命令以清除缓存：root
注意：如果仍然存在错误
如果您使用的是PHP的默认网络服务器（例如php artisan config:cache），则需要重新启动服务器
OR
如果您使用过 XAMPP ，请重新启动 Apache 服务器

在同一个项目/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中运行查询选择、更新、删除等时，会出现此错误。
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，那么您应该为所有数据库使用相同的 DB_USERNAME

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操作：
（这对我有用）
记下您的实际用户名和密码 转到您的 cPanel（如果您使用的是 cPanel） 从数据库选项卡中，选择 MySQL 数据库。 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，这将重新生成具有当前所有者权限的连接。
答案 10 :(得分：-2)
如果您在访问数据库时不需要登录 尝试将数据库用户名作为“root”，密码字段留空 这是解决我的问题
