Powershell 巧克力罐头'；找不到windows功能

我正在使用Octopus deploy在目标计算机上运行PowerShell脚本，试图安装

IIS

。我正在使用下面的脚本并传入必要的参数。记录的内容使人相信呼叫正确，但它只会以以下方式响应：

正在从

chocolate

程序包存储库安装程序包

IIS WebServerRole

代码：

if(-not (Test-Path $chocolateyBin)) {
    Write-Output "Environment variable 'ChocolateyInstall' was not found in the system variables. Attempting to find it in the user variables..."

    throw "Chocolatey was not found at $chocolateyBin."
}

if (-not $ChocolateyPackageId) {
    throw "Please specify the ID of an application package to install."
}

$chocoVersion = & $choco --version

根据我能找到的最新巧克力文档，这应该是可行的。你知道为什么不会吗？我应该提到的是，这是在Azure Windows 2012 R2虚拟机上实现的。

我通过升级到Chocolate的预发布版本，实现了这一点。9.10.x-beta

---

我应该注意到，仅仅做一个-pre不足以让它安装软件包……出于某种原因，我还不得不强迫软件包获得chocolate来更新自己。不确定这是否是出于设计。

你不能在运行触手的用户的机器上手动运行powershell脚本吗？@AlexM-是的，即使我以管理员身份登录机器，我也会收到完全相同的消息。windows功能命令似乎不起作用。我甚至试过一些旧版本的电话，但也不起作用。我不太会吃巧克力，所以我想也许我做错了什么。当然不是故意的。如果你有它不工作的任何日志，我想看看。旁注，

choco升级巧克力-pre

，而不是

choco安装巧克力-pre

/

cinst巧克力-pre

。后两个命令将需要

--force

，因为install是关于获得一些东西的安装，升级将从此开始。嗯。如果是其他原因，请告诉我。我确实确认我正在进行升级…不确定为什么需要强制，如果我再次这样做，我将发送一些日志。酷-请记住日志是以调试/详细格式获取的。所以当你想看的时候，这很有帮助。
