当我运行作曲家更新时，它失败显示错误：
[ComposerDownloaderTransportException]
The "https://packagist.org/packages.json" file could not be downloaded: failed to open stream:
连接被拒绝
如果我从浏览器访问 URL，它会通过，当我尝试从我的终端获取或卷曲 URL 时，它会显示错误：
--2017-02-05 20:41:58-- https://packagist.org/packages.json
Connecting to 127.0.0.1:8888... failed:
Connection refused.
--2017-02-05 20:41:58-- https://packagist.org/packages.json
Connecting to 127.0.0.1:8888... failed: Connection refused.
我认为这是代理连接的东西，但我似乎无法解决问题。
如果我运行作曲家更新 -vv，波纹管是完整的跟踪：

帮助将不胜感激！我似乎无法克服此错误
我在 Ubuntu Linux 16.04 上，下面是我必须做的来解决这个问题，正如我之前提到的，它的代理设置存在一些问题。
步骤 1
- 转到系统设置
- 网络
- 网络代理
- 将其更改为无
- 最后单击应用系统范围
步骤 2
- 打开终端并键入以下命令。
unset https_proxy && unset socks_proxy && unset ftp_proxy
最后重新启动系统。上面的解决方案为我解决了问题。
该行using proxy 127.0.0.1:8888表示您的系统有问题。我可以猜到这是一个非常激进的防病毒软件。除非必须通过代理连接，否则您没有理由在端口 8888 上连接到本地主机。你能做什么？检查防病毒设置并关闭通过 HTTPS 的安全连接检查。
