Also having problems using gr-osmosdr sink

I Tried what Nick suggested and when I ran;

python gen_osmosdr_blocks.py osmosdr_sink.block.yml

the following error appears
Traceback (most recent call last):
File "gen_osmosdr_blocks.py", line 388, in
params = ''.join([
File "gen_osmosdr_blocks.py", line 389, in
parse_tmpl(PARAMS_TMPL, n=n, sourk=sourk)
File "gen_osmosdr_blocks.py", line 350, in parse_tmpl
from mako.template import Template
ModuleNotFoundError: No module named 'mako'

Any ideas?
