Positional Parameter error in powershell script

问题

I was trying to install/update EPO agent through PowerShell, but I am getting below error. I am new to PowerShell so I am not able to see what is causing this.

Below is the script I used to update the agent :

Start-Process -FilePath $scriptpath "\INAEPO01_Framepkg.exe" "/FORCEINSTALL" "/INSTALL=AGENT" -Wait

Error :

Positional parameter cannot be found that accepts argument /FORCEINSTALL.

回答1:

Try it like that, i.e. add commas between the arguments so that they form an array

Start-Process -FilePath $scriptpath "\INAEPO01_Framepkg.exe","/FORCEINSTALL", "/INSTALL=AGENT" -Wait  

or to be more explicit

Start-Process -FilePath $scriptpath -ArgumentList "\INAEPO01_Framepkg.exe", "/FORCEINSTALL", "/INSTALL=AGENT" -Wait
