powershell - 未加载 SQLASCmdlets，因为在任何模块目录中都找不到有效的模块文件

Question

我有一个由于缺少 SQLASCmdlets 模块而失败的脚本。

The specified module 'SQLASCmdlets' was not loaded because no valid module file was found in any module directory.

为了运行它，我知道我需要 SQLPS，我可以使用它找到

Get-Module -ListAvaiable

ModuleType Version    Name
---------- -------    ---- 
Manifest   1.0        SQLPS 

我已经安装
- SQL 服务器 2016
- SQL 管理工作室 2017

错误:

VERBOSE: ******************************
VERBOSE: The specified module 'SQLASCmdlets' was not loaded because no valid module file was found in any module directory.
VERBOSE: Errors: 1
VERBOSE: ******************************
VERBOSE: System.IO.FileNotFoundException: The specified module 'SQLASCmdlets' was not loaded because no valid module file was found in any module directory.
VERBOSE: ScriptHalted The specified module 'SQLASCmdlets' was not loaded because no valid module file was found in any module directory.

当我再次重新运行我的脚本时，它可以工作。我如何使它第一次工作？

我使用的代码是:

Import-Module "SQLPS" -DisableNameChecking


$sqlsvr = New-Object -TypeName  Microsoft.SQLServer.Management.Smo.Server("WIN-C0BP65U3D4G")
$restore = New-Object -TypeName Microsoft.SqlServer.Management.Smo.Restore
$devicetype = [Microsoft.SqlServer.Management.Smo.DeviceType]::File

$files = gci C:\psbackups

$BackupFiles = @()

foreach ($file in $files){
    $restoredevice = New-Object -TypeName Microsoft.SQLServer.Management.Smo.BackupDeviceItem($file.FullName,$devicetype)

    $restore.Devices.add($restoredevice)
    $errcnt=0
    try{
        $restore.ReadMediaHeader($sqlsvr)
    }
    catch [System.Exception]{
        Write-Output "$file is not a sql backup file `n"
        $errcnt =1
    }
    finally {
        if ($errcnt -ne 1){
            Write-Output "$file is a sql backup file `n"
            $BackupFiles += $file
        }
        $errcnt = 0
    }
    $restore.Devices.remove($restoredevice)
    Remove-Variable restoredevice
}

Answer 1

经过2小时的研究，我找到了解决方案。

安装SqlServer包

https://www.powershellgallery.com/packages/SqlServer/21.0.17199

2.我已更新我的脚本以选择特定版本以防安装

# import modules 
if ((Get-Module -ListAvailable | where-object {($_.Name -eq 'SqlServer') -and ($_.Version.Major -gt 20) } |Measure).Count -eq 1){
    # implementation of new sql modules migated into new location
    Import-Module SqlServer -DisableNameChecking -Verbose
}
else{
    # fallback for SQLPS 
    Import-Module SQLPS -DisableNameChecking -Verbose
}

确保我有你的 PowerShell 的新 session 。
