PowerShell安装NuGet，说无法上网，但我其实可以 [英] PowerShell Installing NuGet, says unable to access internet, but I actually can
问题描述
我按照在代理后使用PowerShell中提到的步骤进行配置我的代理服务器.
I followed the steps mentioned in Using PowerShell Behind a Proxy to configure my proxy server.
netsh winhttp set proxy "[IP]:[Port]"
$Wcl = New-Object System.Net.WebClient
$Creds = Get-Credential
$Wcl.Proxy.Credentials = $Creds
弹出一个对话框，在第三行收集我的凭据.
A dialog popped up to collect my credential on the third line.
然后我尝试安装 NuGet:
Then I tried to install NuGet:
PS C:UsersAdministrator> Install-PackageProvider -Name NuGet -MinimumVersion 2.8.5.201 -Force
WARNING: Unable to download from URI 'https://go.microsoft.com/fwlink/
?LinkID=627338&clcid=0x409' to ''.
WARNING: Unable to download the list of available providers. Check your internet
connection.

for the provider 'NuGet'. The package provider requires 'PackageManagement' and
'Provider' tags. Please check if the specified package has the tags.

错误消息似乎表明我的 PowerShell 无法连接到互联网，但是当我尝试此命令时:
The error message seems to indicate my PowerShell cannot connect to internet, but when I tried this command:

看来还是可以上网的.
我做错了什么?如何安装 NuGet?

我尝试了 Ocaso Protal 的建议:

好像没有效果.
推荐答案
可能与 TLS 安全相关(参考:https://rnelson0.com/2018/05/17/powershell-in-a-post-tls1-1-world/)
could be TLS security related (ref: https://rnelson0.com/2018/05/17/powershell-in-a-post-tls1-1-world/)
先试试这个命令:
[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
然后尝试进行更新.注意:该命令只影响当前会话，不会持续存在.
then try to do the update. Note: the command only affects the current session and does not persist.
您还可以检查计算机上设置的客户端 TLS 版本.看起来需要客户端的 TLS 1.0.(参考:https://powershell.org/forums/topic/wmf-5-1-upgrade-broken-repositories/)
You may also check what version of TLS for client is set on computer. Looks like TLS 1.0 for client is required. (ref: https://powershell.org/forums/topic/wmf-5-1-upgrade-broken-repositories/)
