无法以管理员身份在新安装的 Windows Server 2016 上安装 NuGet？

Question

我使用的是 Windows Server 2016 和 ADFS 4.0。

作为 AD 联合服务故障排除的一部分，这要求我按照https://adfshelp.microsoft.com/diagnosticsanalyzer/Analyze安装 NuGet 和模块

这是我执行的内容和错误：

Install-Module -Name ADFSToolbox -Force
Import-Module -Name ADFSToolbox -Force
Install-PackageProvider -name NuGet -MinimumVersion 2.8.5.201 -Force

错误：

强制 PowerShell 使用 TLS 1.2，然后执行您的命令。我在 TLS 1 的截止日期之后遇到了这个问题：

[System.Net.ServicePointManager]::SecurityProtocol = [System.Net.SecurityProtocolType]::Tls12;
