Composer 更新不运行

Question

当我运行作曲家更新它失败显示错误：

[Composer\Downloader\TransportException]                                                                           
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，当我尝试 wget 或 curl 从终端访问 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.

我认为它与代理连接有关，但我似乎无法解决问题。

如果我运行 composer update -vv，下面是完整的跟踪：

我们将不胜感激！我似乎无法克服这个错误

Answer 1

我在 Ubuntu Linux 16.04 上，下面是我必须解决的问题，正如我之前提到的它与代理设置有关的一些问题。

第一步

• 转到系统设置
• 网络
• 网络代理
• 将其更改为无
• 最后点击应用系统范围

第 2 步

• 打开终端并输入以下命令。
  unset https_proxy && unset socks_proxy && unset ftp_proxy

最后重新启动您的系统。上面的解决方案为我解决了问题。

Answer 2

using proxy 127.0.0.1:8888 行表明您的系统存在问题。我可以猜到这是一个非常激进的杀毒软件。除非您必须通过代理连接，否则您应该没有理由在端口 8888 上连接到 localhost。你能做什么？检查防病毒设置并关闭对通过 HTTPS 的安全连接的检查。
