代理后面的作曲家，设置，仍然无法正常工作

Question

我在代理后面有带有 Ubuntu 14.04 的 VirtualBox。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。并据此：

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 设置为使用代理。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
[Composer\Downloader\TransportException]                                                 
  The "https://packagist.org/packages.json" file could not be downloaded: php_network_getaddresses: getaddrinfo failed: No address associated with hostname

任何建议表示赞赏。

Answer 1

请尝试将HTTP_PROXY设置为环境变量

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

也许是export HTTPS_PROXY_REQUEST_FULLURI=0。

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

（当诊断命令未正确报告环境问题时，可能是 Composer 错误。）

错误消息php_network_getaddresses: getaddrinfo failed: No address associated with hostname 表示DNS 问题。

似乎没有正确配置代理的 DNS 解析。

请尝试将您的 /etc/resolv.conf 文件中的名称服务器更改为其他名称服务器，例如sudo echo "nameserver 8.8.8.8" >> /etc/resolv.conf.

那么你可以pingPackagist 的 URL 和 IP 地址。

请求网址（主机名）：https://packagist.org/
