【问题描述】：
我有一个 Laravel 项目。我想在我的 laravel 环境中使用数据库（mysql）。如果我将手动创建我的数据库和表，它就可以工作。但是，如果我尝试使用 composer 和 php artisan，我会遇到以下错误：
C:\Projects>composer update
Loading composer repositories with package information
Updating dependencies (including require-dev)
Nothing to install or update
Generating optimized autoload files
> Illuminate\Foundation\ComposerScripts::postAutoloadDump
> @php artisan package:discover --ansi
In Model.php line 1253:
Call to a member function connection() on null
Script @php artisan package:discover --ansi handling the post-autoload-dump event returned with error code 1
C:\Project>
我在我的项目中使用 Laravel 5.8。如果您检查我的应用程序配置文件，您就可以理解，我想要做什么:) 以及我的 config/app.php 文件如下：
<?php
use Illuminate\Database\Eloquent;
if(\App\Http\Controllers\System\ConfigValue::get('timezone') !== false) {
$timezone = \App\Http\Controllers\System\ConfigValue::get('timezone');
} else {
$timezone = 'UTC';
}
if(\App\Http\Controllers\System\ConfigValue::get('language') !== false) {
$language = \App\Http\Controllers\System\ConfigValue::get('language');
} else {
$language = 'en';
}
return [

我想在我的 laravel 环境中使用它。你能帮我解决这个问题吗？下面是我的 ConfigValue 类：
<?php
namespace App\Http\Controllers\System;
use App\SystemConfig;
use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
class ConfigValue extends Controller
{
public static function get($variable) {
if(SystemConfig::where('variable', $variable)->value('value')) {
return SystemConfig::where('variable', $variable)->value('value');
} else {
return false;
}
}
public static function set($variable, $value) {
$system_config = SystemConfig::find($variable);
$system_config->value = $value;
if($system_config->save()) {
return true;
} else {
return false;
}
}
}
我正在从数据库中获取所有变量，例如 top。对我有什么想法吗？感谢您的回复:)
