如何为powershell查找有关xml-rpc的更多信息？

当我运行Update-help时，我希望能找到更多信息。

也许添加一个模块？

我试过了：

nicholas@mordor:~/powershell$ 
nicholas@mordor:~/powershell$ pwsh hello.ps1 
Import-Module: /home/nicholas/powershell/hello.ps1:1
Line |
1 |  import-module RPC-Client
|  ~~~~~~~~~~~~~~~~~~~~~~~~
| The specified module 'RPC-Client' was not loaded because no valid module file was found in any module directory.
hello
nicholas@mordor:~/powershell$ 
nicholas@mordor:~/powershell$ cat hello.ps1 
import-module RPC-Client 

"hello"
nicholas@mordor:~/powershell$ 

如何将其添加到powershell核心？

我尝试安装为：

但可能需要"；下载"；首先？类似于：

sudo powershell -Command {Install-Module -Name AzureRM.Netcore}

或者至少沿着这些线。

Answer 1

PowerShell中没有内置XML-RPC功能。

因此，提供这样的功能需要第三方代码。

在您的情况下，您的脚本似乎需要XmlRpc模块，该模块可从PowerShell库中获得(这意味着您可以使用Install-Module XmlRpc安装它(。

然而，该模块上一次更新是在5年多前，早于PowerShell的跨平台版本PowerShell(Core(，因此您必须自己了解它是否适用于Ubuntu等类似Unix的平台。

Untrusted repository
You are installing the modules from an untrusted repository. If you trust this repository, change its InstallationPolicy value by 
running the Set-PSRepository cmdlet. Are you sure you want to install the modules from 'PSGallery'?
