Unable to get protobuf 2.6.1 working with python2.7

[Arun Chandrasekaran]

Hi,

I am on Ubuntu 14.10 and I'm using protobuf 2.6.1, built from source.

When I try to run the python protobuf tests, I get the below error.

$ python setup.py google_test

ImportError: cannot import name unittest_pb2

Ignoring the above test failure, I did a sudo python setup.py install.

After this, I'm not able to import the generated proto files. Please see below.

msg.proto

message msg {

    required int64 value = 1;

}

$ protoc --version

libprotoc 2.6.1

$ PYTHONPATH=gen python

Any idea where I am going wrong?

Thanks,

I have got the same issue. Is there any work around.
After I ignored it. Got an ImportError that
from google.protobuf.pyext import _message not found.
