代理后的作曲家，设置，仍然不能工作

Question

我有VirtualBox与Ubuntu 14.04后面的代理。我已经安装了Apache2, PHP, MySQL和Composer。我做了谷歌，设置了系统范围的代理，apt-get和git的代理。根据这个:

deralsem@DerVirtualBox:/var/www/laravel$ composer diag
Checking composer.json: OK
Checking platform settings: OK
Checking git settings: OK
Checking http connectivity to packagist: OK
Checking https connectivity to packagist: OK
Checking **HTTP proxy**: OK
Checking **HTTP proxy support for request_fulluri**: OK
Checking **HTTPS proxy support for request_fulluri**: OK
Checking github.com rate limit: OK
Checking disk free space: OK
Checking composer version: OK

Composer设置为代理使用。但是，试试这个:

$ cd /var/www
$ git clone https://github.com/laravel/laravel.git
Navigate to Laravel code directory and use composer to install all dependencies required for Laravel framework.
$ cd /var/www/laravel
$ sudo composer install

我有这个:

Loading composer repositories with package information
[ComposerDownloaderTransportException]                                                 
  The "https://packagist.org/packages.json" file could not be downloaded: php_network_getaddresses: getaddrinfo failed: No address associated with hostname

欢迎指教

请尝试将HTTP_PROXY设置为环境变量

HTTP_PROXY='http://the.proxy'
export HTTP_PROXY
php composer.phar install

和

HTTPS_PROXY_REQUEST_FULLURI=0
export HTTPS_PROXY_REQUEST_FULLURI

引用:https://getcomposer.org/doc/03-cli.md http-proxy-or-http-proxy

(当诊断命令没有正确报告环境问题时，可能是Composer的错误。)

错误信息php_network_getaddresses: getaddrinfo failed: No address associated with hostname表示DNS问题。

似乎代理的DNS解析配置不正确。

请尝试将/etc/resolv.conf文件中的名称服务器更改为其他名称服务器，例如Google Inc.，通过附加其中一个DNS服务器IPv4地址(resolv.conf(5)):

sudo printf 'nnameserver 8.8.8.8n' >> /etc/resolv.conf

然后您可以ping的URL和Packagist的IP地址。

请求URL(主机名):https://packagist.org/

远程地址:87.98.253.214:443
