安装laravel依赖与作曲家不工作 [英] installing laravel dependencies with composer not working

问题描述

我正在尝试使用本指南安装Laravel Excel / p>

我已经在我的composer.json中包含了这个行;

 需要：{
laravel / framework：4.2。*，
maatwebsite / excel：1. *
}，
  

然后我尝试使用命令 composer update 更新作曲者。这导致以下消息....

 警告：这个作曲家的开发构建是超过30天。建议通过运行/ usr / local / bin / composer self-update来更新它以获取最新版本。 
 
加载包信息的作曲家资料库
 
无法下载https://packagist.org/packages.json文件：php_network_getaddresses：getaddrinfo failed：名称或服务不知道
 
无法打开流：php_network_getaddresses：getaddrinfo失败：名称或服务未知
 
 https://packagist.org无法完全加载，包信息已加载从本地缓存可能已经过时
 
更新依赖关系（包括require-dev）

当我尝试自己更新作曲者（按警告消息建议）我得到以下内容：
  [Composer\Downloader\TransportException] 
无法下载https://getcomposer.org/version文件：php_network_getaddresses：getaddrinfo failed：Name或服务不知道
无法打开流：php_network_getaddresses：getaddrinfo失败：名称或服务未知
  
所以我的第一个问题是我无法更新作曲家。
 
 
 
我的第二个问题是，我不认为Laravel Excel已经安装，因为我看不到它在供应商/ laravel目录在任何地方（不是所有的依赖关系通常存储在哪里？）
 
 
 
我是一个完整的初学者，当涉及到使用作曲家和安装依赖关系，我甚至没有真的甚至使用一个JSON文件，直到现在，所以真的很挣扎在这里... 
解决方案
我遇到同样的问题。后来，我知道我的代理不允许我更新作曲家。所以，检查您的代理设置。
 
I'm trying to install Laravel Excel using this guide

I have included the line in my composer.json;
"require": {
    "laravel/framework": "4.2.*",
    "maatwebsite/excel": "1.*"
},
I am then attempting to update composer using the command composer update. This results in the following messages....
Warning: This development build of composer is over 30 days old. It is recommended to update it by running "/usr/local/bin/composer self-update" to get the latest version.

Loading composer repositories with package information

When I try to self-update composer (as recommended in the warning message) I get the following;
[Composer\Downloader\TransportException]
  The "https://getcomposer.org/version" file could not be downloaded: php_network_getaddresses: getaddrinfo failed: Name or service not known
  failed to open stream: php_network_getaddresses: getaddrinfo failed: Name or service not known
So my first problem is that I cannot update composer.

My second problem is that I do not think Laravel Excel has been installed because I cannot see it in the vendor/laravel directory anywhere (isn't that where all the dependencies are usually stored?)

I am a complete beginner when it comes to using composer and installing dependencies and I've not really even used a JSON file before until now so really struggling here...
解决方案
I had faced the same problem. Later, I came to know that my proxy not allowing me to update the composer. So, check your proxy settings.
