Php Laravel 5-未知数据库

我正在尝试用laravel 5制作一个登录表单

每次我尝试登录时都会出现错误

Connector.php第55行出现异常：SQLSTATE[42000][1049]未知 数据库“php2project”

但是，数据库仍然存在。

我可以毫无问题地使用“php artisan migrate”，所以我不知道现在为什么会出现这个问题

下面是我的.env文件的外观

APP_ENV=local
APP_DEBUG=true
APP_KEY=_STACK_

DB_HOST=127.0.0.1
DB_DATABASE=php2project
DB_USERNAME=root
DB_PASSWORD=_STACK_

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

编辑：这是我的配置/数据库信息

'default' => env('DB_CONNECTION', 'mysql'),

首先检查.evn中是否设置了正确的凭据

如果是，则尝试缓存配置。有时可能会出现问题，因为您在.env中进行了更改，但没有缓存它（仅当您在项目中缓存配置时）

尝试运行
php artisan cache:config
在config->database.php中，您的数据库设置为forge，而.env文件中的数据库名称为php2project。确保两个文件中的内容相同，另外，密码在config->database.php中为空，但在.env文件中设置为_STACK_uuu，并确保您的用户名在这两个文件中相同。
您可以发布以下内容：
app/config/database.php
？您正在使用哪个环境？@Daan更新了您通过
php artisan运行此文件的OPAre有机会发球吗？在
service
命令启动后，您是否对
.env
文件进行了任何更改？我看到您正在使用laravel的
auth
您是否可以查看
app/config/auth.php
中的驱动程序是否设置为eloquent或database？如果口才好，你能发布用户模型吗？
@extends('layouts.master')
@section('title', 'Login')
