我该如何解决？
在您的根目录中放置一个 .env 文件，然后将此代码粘贴到那里。
APP_ENV=local

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。在您的配置文件中 env() 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。
您可以通过以下方式检查当前环境：php artisan env
下一个
- 在 config/development 下创建 |暂存（文件夹）

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

并在您的 .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 命令应该可以顺利运行。
如果您在访问数据库时不需要登录
尝试将数据库用户名设为root，密码字段留空
这解决了我的问题
DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=YOUR_DATABASE_NAME
DB_USERNAME=root
DB_PASSWORD=
如果您在 XAMPP 中安装 MySQL 时没有默认用户名，则应将 DB_USERNAME= 设置为 root。
此问题可能是由于文件没有预期的“.env”扩展名造成的。
如果您在 Windows 中隐藏了文件扩展名（默认情况下打开），那么它很容易 看起来 就像扩展名是“.env”，当它实际上类似于“.env.txt”。
这意味着该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 等编辑器打开文件，您将看到 实际 扩展名是什么。如果它有“.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。 SQLSTATE 错误消息直接从 MySQL.
传递
然后我删除了数据库和用户。 Re-created PhpMyAdmin 的数据库选项卡中的数据库。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 客户端和 运行 迁移连接。
我们忘记在 .env 文件中设置 DB_USERNAME=，所以我们得到这个错误：
SQLSTATE[HY000] [1044] Access denied for user ''@'localhost' to
database 'forge'
打开.env文件并编辑它。只需设置正确的数据库凭据：
DB_USERNAME= //Your Database Username
如果安装时没有默认用户名，DB_USERNAME应设置为root
更改 .env 后，在您的终端中输入此命令以清除缓存：php artisan config:cache
注意：如果还是报错
如果您使用 PHP 的默认 Web 服务器（例如 php artisan serve），您需要 重新启动 您的服务器
或
如果您使用过 XAMPP 然后重新启动您的 Apache 服务器
当您在同一个 project/query
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 都是不同的，所以当我 运行 从多个数据库查询 select、更新、删除等时，就会出现此错误。
因为如果您在查询中使用多个 table 并且数据库 DB_USERNAME 不同，您将收到此错误。
解法：
如果您 using/connect 多个数据库，那么您应该对所有数据库使用相同的 DB_USERNAME
更改帐户所有权后遇到同样的问题，所以我最终执行了以下操作：
（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）
在“数据库”选项卡中，select MySQL 个数据库。
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。
