python3 run.py: infinite loop

[taiqn]

I setup from source, when running python3 run.py, infinite loop occurred, stop Terminal with output:

from django.core.wsgi import get_wsgi_application\nModuleNotFoundError: No module named 'django'\n[2022-07-17 18:32:48 +0700] [20252] [INFO] Worker exiting (pid: 20252)\n[2022-07-17 18:32:48 +0700] [20251] [INFO] Shutting down: Master\n[2022-07-17 18:32:48 +0700] [20251] [INFO] Reason: Worker failed to boot.\n')
Traceback (most recent call last):
File "run.py", line 46, in
os.killpg(os.getpgid(proc.pid), signal.SIGTERM)
ProcessLookupError: [Errno 3] No such process

Hope you could fix that.
