无法安装WinSCP PowerShell模块

Question

我正在尝试在Windows 7系统上使用WinSCP PowerShell module。这就是我所做的：

1. 已安装Windows PowerShell 5.0版。
2. 已安装Windows Management Framwork v5.0
3. 以管理员身份启动PowerShell
4. 执行命令Set-ExecutionPolicy Unrestricted
5. 执行命令Install-Module -Name WinSCP（导致无输出）。
6. 当要求下载并安装Yes
时，选择NuGet-anycpu.exe

最后，我通过执行命令Open-WinSCPSession进行了一次健全性检查，结果导致以下错误：

  The term 'Open-WinSCPSession' is not recognized as the name of a cmdlet,
  function, script file, or operable program. Check the spelling of the
  name, or if a path was included, verify that the path is correct and try
  again.
  At line:1 char:1

+ Open-WinSCPSession
+ ~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : ObjectNotFound: (Open-WinSCPSession:String) [], CommandNotFoundException
    + FullyQualifiedErrorId : CommandNotFoundException

这表明该模块未正确安装。关于我做错了什么的任何建议？
