[BUG] ModuleNotFoundError: No module named 'buf' when importing protovalidate about protovalidate-python HOT 7 CLOSED

This is an issue with the documentation. The wheel file doesn't contain the dependency for the provalidate source files and must be generated. Ensure you follow the guide here to generate with buf.

You should have the following source files locally:

gen
└── buf
    └── validate
        ├── expression_pb2.py
        ├── priv
        │   └── private_pb2.py
        └── validate_pb2.py

Now for python to find this package as buf.validate.expression_pb2 the following env variable is required to be set:

PYTHONPATH=gen

from protovalidate-python.

Glad you fixed it. It could be due to not having any imports for the validation library. Check your source files have import "buf/validate/validate.proto"; and use the import to validate. Run buf dep update and check that a buf.lock file is generated with a dep on buf.build/bufbuild/protovalidate. Once you start to use the validation library --inlcude-imports should work.

What should I do if I am using python -m grpcio_tools.protoc instead of buf to compile the proto file?

Thanks @emcfarlane . I found that running buf generate --include-imports does not generate the buf folder as expected, however, running buf generate buf.build/bufbuild/protovalidate does generate the proper folder structure. Any ideas why that might be?

@emcfarlane Thanks! That indeed did fix it. Appreciate the help
