勺子安装时间超时

我想在笔记本电脑上安装scoop，我没有管理员权限。我在PowerShell中使用以下命令：

PS> Set-ExecutionPolicy RemoteSigned -scope CurrentUser
PS> iex (new-object net.webclient).downloadstring('https://get.scoop.sh')
Exception calling "DownloadString" with "1" argument(s): "The operation has timed out"
At line:1 char:1
+ iex (new-object net.webclient).downloadstring('https://get.scoop.sh')
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
    + FullyQualifiedErrorId : WebException

我相信这是因为它默认使用IPv6而不是IPv4：

PS> ping get.scoop.sh
Pinging d19x8hxthvia8.cloudfront.net [2600:9000:2002:7200:1f:b80:d400:93a1] with 32 bytes of data:

PS> ping -4 get.scoop.sh

如何强制iex命令使用IPv4而不是IPv6？

powershell ipv6

请注意，一般情况下，如果操作系统看到IPv6 可以开始使用，则它只会选择IPv6 。您的路由器可能具有部分配置，例如，广告地址前缀但不是默认路由。

通常IPv6应该正常工作。我现在注意到我无法ping谷歌，因为它默认为IPv6。我将调查这是由于笔记本电脑配置错误还是路由器配置错误造成的。

我找到了以下工作解决方案：

PS> Set-ExecutionPolicy RemoteSigned -scope CurrentUser
PS> $wc = new-object net.webclient
PS> $wc.headers.add('host', 'get.scoop.sh')
PS> iex $wc.downloadstring('https://52.85.245.136')
