Error {path_pihole} was not found

[SneakyTax]

Looks like the error is tracking back on this...

pihole-regex/install.py

Line 91 in 22c7d62

path_pihole = docker_mnt_src if docker_mnt_src else r'/etc/pihole'

Is there supposed to be a 'r' before the '/etc/pihole'

/etc/pihole/ is the location when not running docker/etc.
