SyntaxError: invalid syntax when building with python3.

[abcfy2]

I'm using python3 installed by anaconda. But I cannot compile tensorflow-serving:

RROR: /home/fengyu/projects/serving/tensorflow_serving/model_servers/BUILD:181:1: error executing shell command: 'bazel-out/host/bin/external/bazel_tools/tools/build_defs/pkg/build_tar --flagfile=bazel-out/local-py3-fastbuild/bin/tensorflow_serving/model_servers/tensorflow_model_server_tar.args' failed: bash failed: error executing command /bin/bash -c 'bazel-out/host/bin/external/bazel_tools/tools/build_defs/pkg/build_tar --flagfile=bazel-out/local-py3-fastbuild/bin/tensorflow_serving/model_servers/tensorflow_model_server_tar.args': com.google.devtools.build.lib.shell.BadExitStatusException: Process exited with status 1.
