install the required libraries

python3 waybackrobots.py https://www.abc.in/
Found 4 unique results
This may take some time...

File "/home/wizard/BugBountyTool/waybackrobots.py", line 45, in
with open(filename, 'w') as f:
FileNotFoundError: [Errno 2] No such file or directory: 'https://www.abc.in/-robots.txt'

(here the abc has actual domain)

Oh its working fine on my end just install the libraries which he import and save file as waybackrobots.py
