Cannot show status and it does not schedule either

[hainingpan]

Describe the bug
I followed the readme, but did not succeed.
To Reproduce
Create a foo.py

import datetime
import time

stamp = datetime.datetime.now().strftime("%H:%M:%S")
time.sleep(5)

print(f"Foo - {stamp} + 5 seconds")

Then schedule with hickory schedule foo.py --every=10s

Then check the status using hickory status

Expected behavior
Expect the schedule will work and the show the status of all scheduled jobs

Environment:

• OS: [Linux] (Windows subsystem linux 2)
• Version: [Ubuntu 20.04.1 LTS]

Additional context
When I check status, it shows
