PowerShell DSC资源找不到配置关键字

我正在为我们的开发机器进行DSC配置设置。我遇到的要么是我在使用复合资源时出错，要么是我看不到的东西

我可以毫无问题地运行DevMachineConfig.ps1，但是当我使用

DeveloperMachine-ConfigurationData$ConfigurationData

创建MOF文件时，出现以下错误：

PSDesiredStateConfiguration\Configuration : The argument is null. Provide a valid value for 
the argument, and then try running the command again.
At C:\Program Files\WindowsPowerShell\Modules\DeveloperConfig\DSCResources\CreateDomainController\CreateDomainController.schema.psm1:1 char:1
+ Configuration CreateDomainController
+ ~~~~~~~~~~~~~
+ CategoryInfo          : MetadataError: (:) [Configuration], ParentContainsErrorRecordException
+ FullyQualifiedErrorId : ArgumentIsNull,Configuration

我只是不清楚为什么在

Configuration

关键字上出现空值，因为这似乎是内置的DSC

所以我的问题是这是我的错误还是DSC的错误

以下是文件和相关信息 我的“项目”布局：

*模块文件夹连接到$env:ProgramFiles\WindowsPowershell\Modules

DevMachineConfig.ps1 GetDscResources.schema.psm1 CreateDomainController.schema.psm1

}
if（$domainUser.DomainAdmin-eq$True）
{
添加ADPrincipalGroupMembership-Identity$adminUser.Name-MemberOf“域管理员”
}
if（$domainUser.DelegateAccount-eq$True）
{
$rootDse=[ADSI]“LDAP://rootDse”
$principal=新对象Security.principal.NTAccount（“DEV\$（$domainUser.Name）”）
DSACLS“$（$rootDse.defaultNamingContext）”/G“$（$principal）：CA；复制目录更改”
DSACLS“$（$rootDse.configurationNamingContext）”/G“$（$principal）：CA；复制目录更改”
}
}
}

这更像是一个Powershell问题，而不是DSC问题。您有一个带有默认值的强制参数。你应该选择其中一个

---

强制意味着必须提供参数。默认值实际上应该与

强制=$false

一起使用，因为这样它的行为更有意义（如果调用方不提供值，则使用此值）。

我正在移动设备上查看此值，无法真正测试它，但我想知道

[哈希表[]]

是否不可为空？如果默认值改为

@（）

，会怎么样？因此，这比我想象的要容易。原来我在调用一个未定义的变量（

$adminUser

）。结果显示错误报告不正确。你的提示通过检查我的变量帮助我朝着正确的方向前进，我终于注意到了。很高兴这有帮助，@Jason。我知道这是一个较旧的线程，但我发现帮助我找到类似错误的是查看$error变量。它将具有比构建mof文件时显示的一般错误更详细的信息。希望这对其他人有帮助。
