当我运行Update-help 时，我希望能找到more 的信息。

也许添加一个module？

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 核心中？

我尝试安装为：

但也许需要先“下载”它？东西like:

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

或者至少沿着这些思路。

Answer 1

PowerShell 中没有内置 XML-RPC 功能。

因此提供此类功能需要第三方代码。

在您的情况下，您的脚本似乎需要 XmlRpc module，可从 PowerShell 库 here 获得（这意味着您可以使用 Install-Module XmlRpc 安装它）。

但是，这个模块的最后一次更新是在 5 年多以前，早于 PowerShell 的跨平台版本PowerShell (Core)，因此您必须自己确定它是否适用于 Ubuntu 等类 Unix 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'?

看起来很有希望。
