Question

我在托管平台Cloudways上创建了一个新的Laravel应用程序（Laravel 5.7）。 Cloudways很方便，因为您可以直接从其界面安装新的Laravel构建，而不是在本地创建并推送到服务器。

无论如何，我创建了构建，并将文件拉到本地计算机上。在以前的Laravel版本中，我似乎想起来只是能够编辑.env文件以指向我的本地数据库（当前通过MAMP / phpMyAdmin运行）

我确保创建了一个新数据库，然后更新了.env文件以指向该数据库。

但是，每当我尝试运行迁移时，它仍然要指向database.php配置文件中指定的数据库连接。

更新.env文件后，我会尝试同时运行这两个文件：

php artisan config:clear
php artisan cache:clear

但似乎都没有影响。每次尝试进行迁移时，我仍然会遇到错误。

我似乎找不到关于如何从生产数据库中指定其他本地开发数据库的其他文档。

有人可以提供任何帮助吗？

编辑：

在MAMP上，它的本地设置如下：

Host:   localhost
Port:   8889
User:   root
Password:   root

我当前的.env文件内容：

APP_ENV=local

您的mysql配置是硬编码的。您必须像这样更新database.php才能使用.env中的变量：

'connections' => [
    // Other connection options

    'mysql' => [
        // Other mysql options
        'host' => env('DB_HOST', '127.0.0.1'),
        'port' => env('DB_PORT', '3306'),
        'database' => env('DB_DATABASE', 'forge'),
        'username' => env('DB_USERNAME', 'forge'),
        'password' => env('DB_PASSWORD', ''),
        // Other mysql options
    ],
],
