我正在尝试在代理后面的 Windows 上安装 Chocolatey：

@powershell -ExecutionPolicy unrestricted

在电源外壳中我正在执行

$wc=new-object net.webclient;
$wc.Proxy=new-object system.net.WebProxy('<myproxy-ip>:8012',$true);
$wc.Proxy.Credentials = new-object system.net.NetworkCredential('<myusername>','<mypass>');
iex ($wc.DownloadString('https://chocolatey.org/install.ps1'));

我收到以下错误

Exception calling "DownloadString" with "1" argument(s): "The remote server returned an error: (407) Proxy Authentication Required."
At line:1 char:1
+ iex ($wc.DownloadString('https://chocolatey.org/install.ps1'));
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
    + FullyQualifiedErrorId : WebException

我使用与启动 firefox/iexplorer 时必须输入的用户名/密码相同的用户名/密码（参见图片）。没有为代理配置默认用户名/密码，因为我必须始终输入它们。

更多详细信息（在私有窗口上的 firefox 中使用 Inspect Element）
