Question

我是一名学生，对PowerShell还是很陌生。

我正试图让我的CStringT进行远程下载，但是我一直遇到错误。

#!/usr/bin/env python
import sys, subprocess, os

TOOLS = ['bcompare', 'meld']

def getTool():
    for tool in TOOLS:
        try:

这是我的剧本：

msi

有人可以帮助我吗？任何反馈将不胜感激。

如果您解析的唯一内容是Path的字符串，则不必使$msi成为数组。另外，如果解析"\Path to msi"，为什么还要在Invoke-Command中使用$msi？

编辑：您应该通过msiexec.exe解析-Argumentlist的参数。

尝试一下：

$msi = "Path to msi"

Invoke-Command -ComputerName PCname -ScriptBlock {param($msi) Start-Process msiexec.exe -Wait -ArgumentList "/I $msi /qn /passive"} -ArgumentList $msi

找不到接受参数/安装脚本的位置参数
