Description
We have a Python project which depends on ortools 6.6.4656. Most of the team are on Ubuntu machines, it works fine for them. I'm on a Mac, running macOS 10.13.3 . Whenever I try to run a script that depends on ortools, the process fails and I get the following output in the console:
[libprotobuf FATAL external/protobuf_archive/src/google/protobuf/stubs/common.cc:79] This program was compiled against version 3.0.0 of the Protocol Buffer runtime library, which is not compatible with the installed version (3.4.0). Contact the program author for an update. If you compiled the program yourself, make sure that your headers are from the same version of Protocol Buffers as your link-time library. (Version verification failed in "ortools/gen/ortools/data/rcpsp.pb.cc".)
libc++abi.dylib: terminating with uncaught exception of type google::protobuf::FatalException: This program was compiled against version 3.0.0 of the Protocol Buffer runtime library, which is not compatible with the installed version (3.4.0).

(Version verification failed in "ortools/gen/ortools/data/rcpsp.pb.cc".)
The versions of ortools and protobuf I actually have installed:
> pip show ortools

When I pip install our project dependencies, pip downloads the following wheel for ortools: Downloading ortools-6.6.4656-cp35-cp35m-macosx_10_6_intel.whl (7.4MB)
I'm not sure where the problem lies or how I should proceed. Any advice would be greatly appreciated!
