(;) ; ls -l
total 0
drwxr-xr-x  3 neo  wheel   96 Dec 13 17:22 common
drwxr-xr-x  3 neo  wheel   96 Dec 13 17:22 locustfiles

Could not find any locustfile! Ensure file ends in '.py' and see --help for available options.

Environment

• OS: MacOS

• Locust version: locust 2.5.1
• Locust command line that you ran: locust
• Locust file contents (anonymized if necessary): no locustfile present, only locustfiles directory present

The locustfiles are named api.py and website.py, but the hierarcy is just an example. I dont know what directory you are looking at...

[Hritik14]

Perhaps, then, adding something like locust -f locustfiles/api.py would help understand that.
I assumed that locustfiles is a special directory name and will consider all the files inside as locustfiles automatically.
