请问下 windows下cmd调用ps脚本报错

请帮忙看看这么cmd调用有问题么，该如何调用

cmd 调用命令为

del exportlog-vds.log
powershell -psc “e:\scripts\vim.psc1” “.\vDSbak.ps1” >> exportlog-vds.log

powershell脚本为

Add-PSSnapin VMware.VimAutomation.Core -ErrorAction SilentlyContinue
Import-Module VMware.VimAutomation.Vds

$vcenter = “172.17.232.112”
$vcenteruser = “work”
$vcenterpw = “1420”
# Connect to vCenter Server
connect-viserver $vcenter -User $vcenteruser -Password $vcenterpw

# Get the vNetwork Distributed switches
$switches=get-vdswitch
#
# Perform the backups
foreach ($switch in $switches)
{
#
# Backup each vNetwork Distributed Switch not including the port groups
export-vdswitch $switches -Withoutportgroups -Description “Backup of $switch without port groups” -Destination “e:\scripts\$switch.without_portgroups.$date.zip”
#
# Backup each vNetwork Distributed Switch including the port groups
export-vdswitch $switches -Description “Backup of $switch with port groups” -Destination “e:\scripts\$switch.with_portgroups.$date.zip”
#
# Backup each port group individually
get-vdswitch $switches | Get-VDPortgroup | foreach { export-vdportgroup -vdportgroup $_ -Description “Backup of port group $($_.name)” -destination “e:\scripts\$($_.name).portgroup.$date.zip”
}
}
