Php 为什么在从GIT检索Laravel项目后运行该项目时会收到此错误消息？控制器可以'；不管用？

我是拉维尔的新手，我有以下问题

我在旧笔记本上开发一个Laravel5应用程序，将代码放在我的GIT存储库中。然后我换上笔记本电脑，从GIT上检查我的Laravel5项目

然后我执行此语句以重新导入依赖项：

composer install

现在我的问题是，我无法访问我的Laravel网站的已开发部分

例如，我有一个控制器类：

class RegistrationController extends Controller {

    public function index(){
        Log::info('index() START');
        return view('/registration/index');

    }

    ..................................................................
    ..................................................................
    ..................................................................
}

index（）方法呈现resources/views/registration/index.blade.php视图

问题是，尝试打开URL时，我会收到以下Laravel错误消息：

Whoops, looks like something went wrong.
Whoops, looks like something went wrong.

[2017-03-08 09:31:37] production.ERROR: RuntimeException: The only supported ciphers are AES-128-CBC and AES-256-CBC with the correct key lengths. in C:\xampp\htdocs\HotelRegistration\vendor\laravel\framework\src\Illuminate\Encryption\Encrypter.php:43
Stack trace:

.............................................................................
.............................................................................
.............................................................................

此外，如果我尝试访问基本URL，我会收到相同的错误消息

其中laravel.dev是一个虚拟主机，以这种方式声明到我的C:\xampp\apache\conf\extra\httpd vhosts.conf文件中：

<VirtualHost *:80>
    DocumentRoot "C:/xampp/htdocs"
    ServerName dummy-host2.example.com
</VirtualHost>

<VirtualHost *:80>
    DocumentRoot "C:/xampp/htdocs/HotelRegistration/public"
    ServerName laravel.dev
</VirtualHost>

其中包括：

|        | GET|HEAD  | registration                     | registration.index   | App\Http\Controllers\RegistrationController@index   | web          |

因此，注册资源似乎与先前的控制器方法正确关联

那么为什么我会遇到这个问题呢？有什么问题？我错过了什么？如何解决此问题

EDIT-1:进入laravel.log文件，我发现了以下错误消息：

Whoops, looks like something went wrong.

因此，问题可能取决于这样一个事实，即我没有更多的.env文件（因为似乎GIT忽略了它）？

是

。GIT忽略了env

文件，就好像你签入了可以看到的

.gitignore

文件并输入了它一样it@linktoahref好的，但可能是我的问题的原因（当我试图打开我的Laravel网站的链接时出现错误消息）错误是由于加密密钥引起的，加密密钥通常位于

.env

文件中，如果您签入

config/app.php

以获取

'key'=>env（'app_key'）），

它正在referenced@linktoahref是的。所以重新配置我的.env文件可以解决我原来的问题吗？是的，它应该可以解决你的问题！
