Question

我正在编写一个Powershell DSC脚本，因此我可以轻松配置开发环境。我试图在不打开GUI的情况下安装Visual Studio 2012 Addons。

我已经下载了Specflow .vsix文件。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命令提示符下的

，它可以顺利运行。但是如果我尝试在DSC脚本资源中做同样的事情，我会遇到问题。将上述命令复制并粘贴到SetScript中会导致VSInstaller.exe导致命令永远不会完成。

因此，我根据Choco Install-VSIX cmdlet尝试了以下内容：

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 }
}

在这种情况下，该命令完成，但VSIXInstall.exe抛出FileNotFound错误，我可以在C：\ Windows \ Temp \

中创建的日志中看到该错误

文件绝对存在;如果我向VSInstaller提供不存在的东西，则会出现以下错误

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.

该脚本在带有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DSC Set-Script运行的脚本显然有些不同。任何想法如何解决修复它？或者另一种方式呢？

VSIX是每个用户需要告诉DSC哪个用户使用PSDscRunAsCredential（在PowerShell 5.0中添加）来安装它。

示例，其中$credential是您要为其安装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
}

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