Powershell Visual Studio 12 VSIXInstaller在DSC脚本中运行时报告FileNotFoundException

我正在编写Powershell DSC脚本，以便轻松配置开发环境。我正在尝试在不打开GUI的情况下安装Visual Studio 2012插件

我已经下载了Specflow.vsix文件。当我跑的时候

 & "C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\VSIXInstaller.exe" /q C:\Users\Public\Downloads\TechTalk.SpecFlow.Vs2010Integration.vsix

在Powershell命令提示符下，它工作正常。但是，如果我尝试在DSC脚本资源中执行相同的操作，就会遇到问题。将上述命令复制并粘贴到SetScript中会导致VSInstaller.exe中的命令永远不会完成

因此，基于Choco cmdlet，我尝试了以下方法：

在本例中，命令完成，但vsixanstall.exe抛出一个FileNotFound错误，我可以从C:\Windows\Temp中创建的日志中看到该错误\

文件肯定在那里；如果我向VSInstaller提供了一些不存在的东西，它会出现以下错误

1/18/2017 10:21:45 AM - VSIXInstaller.InvalidCommandLineException: Path to vsix file 'outfile' is invalid or you don't have required access permissions. Please check the path is valid and you have required access permissions.

该脚本正在使用Powershell 5的Windows 7 SP1虚拟机上本地运行。我正在使用具有管理员权限的Powershell ISE执行它

通过dscset脚本运行的脚本显然有些不同。有没有办法解决这个问题？还是另一种方法？

VSIX是针对每个用户的，您需要告诉DSC哪个用户使用

PSDscRunAsCredential

（在PowerShell 5.0中添加）安装此软件

例如，

$credential

是要为其安装VSIX的用户的凭据

Script installSpecflowVS {
        SetScript  = {          
            $specUrl  = 'https://visualstudiogallery.msdn.microsoft.com/9915524d-7fb0-43c3-bb3c-a8a14fbd40ee/file/79327/7/TechTalk.SpecFlow.Vs2010Integration.vsix'
            $outfile  = 'C:\Users\Public\DownloadsTechTalk.SpecFlow.Vs2010Integration.vsix'
            wget $specUrl -outfile $outfile 
            $psi = New-Object System.Diagnostics.ProcessStartInfo
            $psi.FileName='C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\VSIXInstaller.exe'
            $psi.Arguments="/q $outfile"
            $s = [System.Diagnostics.Process]::Start($psi)
            $s.WaitForExit()
            return $s.ExitCode
      }
      TestScript = { return $False }
      GetScript  = { return $True }
      PSDscRunAsCredential = $credential
}

另请参阅如何正确加密

MOF

文件，以免泄露您的凭据。

成功了吗？我也有同样的愿望。正在尝试为安装到Azure Automation帐户上的开发人员计算机编写DSC配置。

Script installSpecflowVS {
        SetScript  = {          
            $specUrl  = 'https://visualstudiogallery.msdn.microsoft.com/9915524d-7fb0-43c3-bb3c-a8a14fbd40ee/file/79327/7/TechTalk.SpecFlow.Vs2010Integration.vsix'
            $outfile  = 'C:\Users\Public\DownloadsTechTalk.SpecFlow.Vs2010Integration.vsix'
            wget $specUrl -outfile $outfile 
            $psi = New-Object System.Diagnostics.ProcessStartInfo
            $psi.FileName='C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\VSIXInstaller.exe'
            $psi.Arguments="/q $outfile"
            $s = [System.Diagnostics.Process]::Start($psi)
            $s.WaitForExit()
            return $s.ExitCode
      }
      TestScript = { return $False }
      GetScript  = { return $True }
      PSDscRunAsCredential = $credential
}
