用嵌套模块加载PowerShell模块产生错误

Question

我已经编写了一个定制的PowerShell模块。我的自定义模块使用SharePoint CMD让。因此，在我的psd1文件中，我有一个嵌套的模块属性，类似于：

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

我是从：PowerShell Modules and SnapIns得到的

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.

Answer 1

最后，我创建了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，添加了以下属性：

ScriptsToProcess = '.\scripts\LoadSharePointPowerShell.ps1'

每当导入模块时，该脚本将运行并加载SnapIn。当模块发布时，不给出错误。
