@sravano9 What platform are you on? Can you share the docker command you're running? These will help me try to reproduce this error.

@bcipriano I am executing this below command inside docker file
RUN python -m pip install -U setuptools

I am using python version 2.7 and Ubuntu Os

please let me know any changes required

Sorry to be clear I mean, can you share the command you're using to actually kick off the docker build. I.e. docker build ....

What version of Ubuntu are you on?

Hi, I'm using Bazel Container Image Rules do build and run a python image, I'm also encountering the same issue, I have tried to upgrade setuptools to lates version, but still getting the same error:

raise SyntaxError(e) from e
                       ^
SyntaxError: invalid syntax

Please feel free to let me know if you need any more information, thanks

@HuanwenChen312 What's the exact version of Python you're using? I.e. the result if you run python --version within your build environment.
