pip installation of py-mini-racer fails

Greetings from Vietnam,

Steps to reproduce

I am running FreeBSD 10.4 with latest updates, and want to install PyMiniRacer as a dependency inside a FreeBSD jail inside a Python 3.6.5 virtual environment. I have installed bash (FreeBSD uses csh by default), as PyMiniRacer seems to depend on it. pip version is 9.0.3; an upgrade to pip version 10.0.1 does not make any difference. After clearing the pip cache, I run from inside the virtual environment:

pip install py-mini-racer

Expected behavior

pip should download and cleanly install PyMiniRacer inside the virtual environment.

Actual behavior

Core error message:

    DEBUG:py_mini_racer.extension.v8_build:Calling: 'fetch v8' from working directory /tmp/pip-build-2jgmbfjh/py-mini-racer/py_mini_racer/extension/v8

                          ^
    SyntaxError: invalid syntax

System configuration

PyMiniRacer version: Tested with 0.1.10 to 0.1.15 Python version: 3.6.5 I tried to run the pip installation process from within csh as well as bash, all within the Python 3.6.5 virtual environment. I am sure I am missing something silly…

Thank you for any ideas or suggestions! Chris

That syntax error is apparently caused by python2

@CodingWithErik You should be able to run it without issues in all the supported platform (we provide wheel for that) This issues appears only if you try to build yourself PyMiniRacer, or we don’t have generated the build for your platform
