Question

我正在尝试做一个简单的作曲家动作（安装laravel），并在大门停下来。

完整的错误消息是

C:\.....\Composer>composer install
Loading composer repositories with package information

  [Composer\Downloader\TransportException]
  The "https://packagist.org/packages.json" file could not be downloaded: failed to open stream: No connection could be made because the target machine actively refused it.

C:\.....\Composer>

Win7 / PHP5.5.8

我正在使用Chrome和IE，两者都使用相同的自动配置脚本（指向“wpad.dat”文件）。

我尝试了以下内容：

诊断中的PHP变量（php -i）

变量=＆gt;值 ...

_SERVER["https_proxy"] => http://172.26.3.10:8080

_SERVER["http_proxy"] => http://172.26.3.10:8080

我错过了什么？我一直在关注各种各样的线程，但我似乎错过了一些非常基本的东西。

ping代理服务器会产生与上述相同IP地址的响应。
将https://getcomposer.org/installer放入浏览器，我收到一个名为installer的文件已下载（在Chrome上）。

Answer 1

我首先要启用作曲家的详细输出，比如

composer -v install

可能会有所启发，但不能保证
