prjxray: bitread: not found

Hi I am trying to use the bit2fasm.py but it shows that bitread is not found

It was working before but it is not working now.

I ran it in the conda env python3 third_party/prjxray/utils/bit2fasm.py --db-root third_party/prjxray-db/artix7 --part xc7a200tsbg484-1 add16.bit

/bin/sh: 1: bitread: not found
