使用嵌套模块加载 PowerShell 模块会出现错误答案

【问题标题】：Loading PowerShell module with nested module giving errors使用嵌套模块加载 PowerShell 模块会出现错误
【发布时间】：2018-09-07 10:21:27
【问题描述】：

我编写了一个自定义 PowerShell 模块。我的自定义模块使用 SharePoint CMD 让。所以在我的 psd1 文件中，我有一个嵌套的模块属性，例如：

NestedModules = @( 'Microsoft.SharePoint.PowerShell',
        '.\Modules\MyModule.psd1')

我来自：PowerShell Modules and SnapIns

当我导入这个模块时，我得到（错误数量的一小部分）：

Import-Module : The following error occurred while loading the extended type data file: Error in TypeData
"Microsoft.Office.Server.Search.Administration.SearchServiceApplication": The member ServiceName is already present.

【解决方案1】：

我最终创建了 PowerShell 脚本来加载 SharePoint PSSnapin。

Begin {
    $SPSnapin = "Microsoft.SharePoint.PowerShell"

    Write-Verbose "The GasuniePowerShell module will try to load the $SPSnapin snappin"  -Verbose

    try {        
        if (Get-PSSnapin $SPSnapin -ErrorAction SilentlyContinue) {
            Write-Verbose "Microsoft.SharePoint.PowerShell Snappin already registered and loaded" -Verbose
        }
        elseif (Get-PSSnapin $SPSnapin -Registered -ErrorAction SilentlyContinue) {
            Add-PSSnapin $SPSnapin
            Write-Verbose "$SPSnapin Snappin is registered and has been loaded for script operation" -Verbose
        }
        else {
            Write-Warning "$SPSnapin Snappin not installed on this server. SharePoint cmdlets disabled." -Verbose
            Exit                
        }
    }
    catch {
        Write-Warning "There was an issue loading the $SPSnapin Snappin. Exiting function." -Verbose
        Write-Warning $_
        Exit  

    }    
}

在我的 PowerShell 模块清单中，我添加了以下属性：

ScriptsToProcess = '.\scripts\LoadSharePointPowerShell.ps1'

每当导入模块时，此脚本都会运行并加载 SnapIn。模块重装时不会出现错误
