Hello! I am making a OS in python, and when I run it I get this in the console:

Repl.it: Updating package configuration

--> python3 -m poetry lock
Updating dependencies
Resolving dependencies...

[InvalidRequirement]
Invalid requirement, parse error at "'os (==0.'"
exit status 1


Repl.it: Package operation failed.'

Could anyone tell me what is going on and how to fix it?'
