Working directory issue

[ShuyingMaggieMi]

When I type "pip install -r requirements.txt "and" python main.py", I got a message in the cmd:
"Exception: proto_root: "/path/to/proto" is not a valid path", how and where I can fix this problem?

Hello, @ShuyingMaggieMi! Please take a look on protobuild.yml and setup correct path to proto_root and other setting properties inside protobuild.yml.
