some problem about sleuth

[namaemonaishi]

while i'm using the command like ./sleuth
it reports that
Traceback (most recent call last):
File "./sleuth", line 46, in
from sleuth import *
File "/usr/local/lib/python3.8/dist-packages/sleuth/init.py", line 2, in
from api_joy import *
ModuleNotFoundError: No module named 'api_joy'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
File "./sleuth", line 49, in
from sleuth_pkg import *
File "/home/lsl/Desktop/joy/sleuth_pkg/init.py", line 1, in
from sleuth import *
File "/usr/local/lib/python3.8/dist-packages/sleuth/init.py", line 2, in
from api_joy import *
ModuleNotFoundError: No module named 'api_joy'

so how to fix it plz
