Question

我正在尝试使用this guide

安装Laravel Excel

我已将该行包含在我的composer.json;

中

"require": {
    "laravel/framework": "4.2.*",
    "maatwebsite/excel": "1.*"
},

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

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

The "https://packagist.org/packages.json" 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

https://packagist.org could not be fully loaded, package information was loaded from the local cache and may be out of date

Updating dependencies (including require-dev)

当我尝试自我更新作曲家时（根据警告信息中的建议），我得到以下内容;

[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

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，因为我无法在vendor / laravel目录中看到它（不是通常存储所有依赖项的地方吗？）

在使用composer和安装依赖项方面，我是一个完全的初学者，直到现在我还没有真正使用过JSON文件，所以真的在这里挣扎......

Answer 1

我遇到了同样的问题。后来，我才知道我的代理不允许我更新作曲家。因此，请检查您的代理设置。

Answer 2

对于Linux用户（Centos 6,7）使用以下命令检查/etc/resolv.conf中的名称服务器是否正常工作

nslookup www.google.com

如果无效，请使用8.8.8.8和8.8.4.4的Google公共名称服务器

nameserver 8.8.8.8
nameserver 8.8.4.4

安装laravel依赖项与composer无法正常工作
