Raspberry Pi lspci not found

I'm trying to flash the efi on 2 macbook pros that have been locked, however it seems when I try to use Pi to search for the chip (or anything for that matter) it returns

pcilib: Cannot open /proc/bus/pci
lspci: Cannot find any working access method.
pi@raspi:~ $

I've tried a google search but i'm not quite sure where to go from here, any help would be greatly appreciated.
I am using Raspberry Pi 2 Model b (40 pins)
thanks guys

Hello, I have the same problem as you. I posted a thread 2 days ago. Did you ever find a solution?
