我試圖在Ubuntu 16.04下載Laravel，但我有麻煩試圖讓作曲家在我們的網絡上工作。我相信這個問題要麼與我們的代理服務器或防火牆有關，這兩者（不幸的）都由我們的上級組織管理。作曲家不工作在代理
我試圖運行這個命令：
sudo composer global require "laravel/installer"
這給了我這個錯誤：當我運行作曲家診斷，我得到下面的輸出
Changed current directory to /home/administrator/.composer
[Composer\Downloader\TransportException]

現在，我已經運行這個命令來設置代理：
export HTTP_PROXY="http://proxy.<url>:8080"
我還修改/etc/profile文件到以下信息添加：
export HTTP_PROXY_REQUEST_FULLURI=0 # or false
export HTTPS_PROXY_REQUEST_FULLURI=0 #
而且我已禁用的IPv6（在/etc/sysctl.conf中）我注意到，在過去已經引起問題：
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1
其中一期工程（如apt-get的使用它），但我似乎無法得到捲曲在所有的工作。我應該設置另一個變量嗎？
