作曲家更新失败并显示“...目标机器主动拒绝连接...”

Question

我正在尝试做一个简单的作曲家动作（安装 laravel），并在门口停下来。

完整的错误信息是

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.

] [-v|vv|vvv|--verbose] [-o|--optimize-autoloader] [-a|--classmap-authoritative] [--ignore-platform-reqs] [--] [<packages>]...

C:\.....\Composer>

Win7/PHP5.5.8

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

我尝试了以下方法：

• 诊断中的 PHP 变量 (php -i)

  变量 => 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？我一直在关注各种线程，但我似乎缺少一些非常基本的东西。

• ping 代理服务器会产生来自与上述相同 IP 地址的响应。

• 将https://getcomposer.org/installer 输入浏览器，我会下载一个名为installer 的文件（在Chrome 上）。

• Composer is not getting installed windows 7

• How to enable PHP's openssl extension to install Composer?

• 详细诊断

`C:\xampp\htdocs>composer -v global require "laravel/installer"

Changed current directory to C:/Users/.../AppData/Roaming/Composer

[Composer\Downloader\TransportException]

Answer 1

我会从启用作曲家的详细输出开始，比如

composer -v install

可能会有所启发，但不能保证
