在Laravel中，我的终端php artisan给null上的成员函数connection调用错误

编程问答 2022-06-06

问题描述

Laravel 5.8.0

我在Laravel有项目。它有很多问题，首先要在虚拟主机上运行它。当我尝试解决它时，我通过命令php artisan serve运行它。不幸的是，我发现每个php artisan命令都给我同样的错误：

In Model.php line 1058:

  Call to a member function connection() on null

在Model.php的这一行中，我有：

   * @param  string|null  $connection
     * @return \Illuminate\Database\Connection
     */
    public static function resolveConnection($connection = null)
    {
        return static::$resolver->connection($connection);
    }

我不知道到底是什么问题，为什么这个$ connection为空。

编辑：

我在我的database.php和.env文件下面添加：

APP_ENV=local
APP_KEY=base64:2OWwGrH6hL+4MKkV7sZZ21MTjSHv/zacUDC67FWVBa4=

return [

        'sqlite' => [

关于Model.php和$ resolver，里面有代码：

use Illuminate\Database\ConnectionResolverInterface as Resolver;
    * @var \Illuminate\Database\ConnectionResolverInterface
     */
    protected static $resolver;

我已经针对此问题进行了一些研究，并对我的问题做了一些处理。在尝试了一些建议后，我去了这个地方，那里有新的错误：

Fatal error: Uncaught ReflectionException: Class config does not exist in C:\xampp\htdocs\jjk\laravel_core\vendor\laravel\framework\src\Illuminate\Container\Container.php:788

我试图搜索解决方案，但没有任何帮助。有人知道吗？
