sql-server - 即使安装了模块，也获取未定义的 DSC 资源“SqlSetup”

Question

我正在尝试通过 DSC 安装 SqlServer，但我一直遇到此错误

Exception calling "NewScriptBlock" with "1" argument(s): "At line:10 char:5
+     Import-DscResource -ModuleName 'SqlServerDsc'
+     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Could not find the module 'SqlServerDsc'.

At line:438 char:9
+         SqlSetup 'InstallDefaultInstance'
+         ~~~~~~~~

我的 DSC 配置片段如下所示

Configuration InstallSoftware
{
param
(
    $ComputerNames
)
Import-DSCResource -ModuleName PSDesiredStateConfiguration
Import-DSCResource -Module SqlServerDsc

Node $ComputerNames
{
    WindowsFeature 'NetFramework45'
    {
        Name   = 'NET-Framework-45-Core'
        Ensure = 'Present'
    }

    SqlSetup 'SqlInstall'
    {
        InstanceName        = 'localhost\mssql2019'
        Features            = 'SQLENGINE'
        Action              = 'Install';
        SourcePath          = 'C:\SQL2019'
        SQLSysAdminAccounts = @('Administrators')
        DependsOn           = '[WindowsFeature]NetFramework45'
    }  
}

InstallSoftware 

我非常肯定 SqlServer 已安装在远程服务器中。

1. Get-DscResource -Module SqlServerDsc 返回资源列表
2. 并且该文件夹存在于 C:\Program Files\WindowsPowerShell\Modules\SqlServerDsc

非常感谢任何反馈/建议。非常感谢您的参与。

看起来这已经被回答了，我不确定我是否正在关注所有内容，但我通常会创建一个包装函数来复制资源。如下所示，带有用于指定路径、服务器、凭据的标志，然后是帮助程序，例如更改最大信封大小（如果你没有点击这个，你会的）并复制我的证书。下面不是全部，但至少可以确保您的模块可以复制。

        [Parameter(Mandatory=$true)]
        [string]$localpath,
        [Parameter(Mandatory=$true)]

        [Parameter(Mandatory=$true)]
        [PsCredential]$PsAdmin,
        [Parameter(Mandatory=$true)]

    #Create Path if it doesnt exist
    if (!(test-path -path $localpath)) {
        New-Item -ItemType directory -Path $localpath
        }
        if ($MaxEnvelope -eq $true)
