使用Powershell使用Invoke-Command远程安装Python失败

Question

I am trying to use this script to install Python on the remote computer. If I run this file directly on the server. This is the Python_Pip_Proxy_PyWinAuto.ps1 file. It works.

Set-ExecutionPolicy -ExecutionPolicy Unrestricted
Write-Host("Hi")
$installer="C:\temp\python-3.6.2.exe"
& $installer /quiet PrependPath=1 InstallAllUsers=1 TargetDir="C:\Python36"

However if I run the Invoke-Command using the following script to run this remotely on the same server, It print's the Hi message so I know that the file is running but Python doesn't get installed.

# Getting the list of servers from a .txt file to an array #

$SRVListFile = "C:\Scripts\ServerList.txt"
$SRVList = Get-Content $SRVListFile -ErrorAction SilentlyContinue

# Copying the .exe file from a shared location to each server in the array #
# Invoking the .ps1 file which runs natively on each server #

Foreach($computer in $SRVList) {

    Get-Service remoteregistry -ComputerName $computer | start-service
    Copy-item -Path "E:\Software\python-3.6.2.exe" -Destination \\$computer\c$\temp -Recurse
    Copy-item -Path "C:\My Files\Work\Episode 003 - MongoDB Back Up\Python_GUI.py" -Destination \\$computer\c$\temp -Recurse
    Invoke-Command -ComputerName $computer -FilePath "C:\My Files\Work\Episode 003 - MongoDB Back Up\Python_Pip_Proxy_PyWinAuto.ps1"
}

What is going wrong. What should I change the code to?

Answer 1

Try using the -scriptblock {Your command here} parameter to execute the command inside the scriptblock parenthesis on the remote computer.

Perhaps you can do it like

$Scriptblock = {
PowerShell -file "C:\My Files\Work\Episode 003 - MongoDB Back Up\Python_Pip_Proxy_PyWinAuto.ps1"

"This is Working" | out-file "C:\Hi.txt"
}
Invoke-Command -ComputerName $computer -Scriptblock $Scriptblock

You might want to remove the Write-Host "Hi" part because that gives the script an interactive nature. If you want to check for execution on remote computer, you can use out-file cmdlet to create a file on the remote computer as an indication.
