我得到了一个laravel项目的git副本，管理员给了我一个sql，说我需要导入它并配置laravel来启动这个项目。
我已经尝试了很多方法，比如 https://gist.github.com/hootlex/da59b91c628a6688ceb1 除了重新安装composer和尝试将db上传到phpmyadmin之外，我还不断遇到错误： composer install 给予

> Illuminate\Foundation\ComposerScripts::postAutoloadDump
> @php artisan package:discover

In Connection.php line 664:
 SQLSTATE[HY000] [1049] Unknown database 'dbname' (SQL: select * from `system_configs`)

In PDOConnection.php line 50:
 SQLSTATE[HY000] [1049] Unknown database 'dbname'

In PDOConnection.php line 46:
 SQLSTATE[HY000] [1049] Unknown database 'dbname'

Script @php artisan package:discover handling the post-autoload-dump event returned with error code 1
``` `composer.phar install` 退货
Could not open input file: composer.phar `php artisan serve` 给予

In Connection.php line 664:
SQLSTATE[HY000] [2002] No connection could be made because the target machine actively refused it.
(SQL: select * from system_configs)
In PDOConnection.php line 50:
SQLSTATE[HY000] [2002] No connection could be made because the target machine actively refused it.
In PDOConnection.php line 46:
SQLSTATE[HY000] [2002] No connection could be made because the target machine actively refused it.

根本没有 `PDOConnection.php` 以及 `database.php` 似乎和我在网上看到的一致 `.env` 文件。
我有一种感觉，我错过了一件非常简单的事情——当你必须导入一个管理员说是执行它的关键的sqldb时，你如何在git copy laravel项目中工作？
