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
