Cannot install warlock==1.3.2 using Python 2.7

[vijay-avi]

Attempting to install warlock==1.3.2 on a Python virtual environment (with Python==2.7.12 and pip==19.1.1, and setuptools==41.0.1) is resulting in the following error
$>virtualenv test-venv $>source test-venv/bin/activate $>python --version Python 2.7.12 $>pip --version pip 19.1.1 from <pip path inside virtual environment> $> pip install warlock Collecting warlock==1.3.2 Using cached https://files.pythonhosted.org/packages/7e/9b/648ceb3bc527e821c04d69f14facb0655268288ac7d8d6aa3a026c3316ea/warlock-1.3.2.tar.gz ERROR: Complete output from command python setup.py egg_info: ERROR: Traceback (most recent call last): File "<string>", line 1, in <module> File "/tmp/pip-install-V0WEIx/warlock/setup.py", line 37, in <module> long_description=read("README.md"), File "/tmp/pip-install-V0WEIx/warlock/setup.py", line 28, in read os.path.join(os.path.dirname(__file__), fname), "r", encoding="utf-8" TypeError: 'encoding' is an invalid keyword argument for this function ---------------------------------------- ERROR: Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-install-V0WEIx/warlock/

I think the 'encoding' parameter is unavailable to open() in Python 2.7.12. To backport open() of Python 3 to Python 2.6/2.7, io.open can be used.
Source: Accepted solution from this StackOverflow thread.

Sorry for all the trouble, still warming up to this. 🙈 Will publish 1.3.3 to PyPi in a bit.

[janw]

Again, sorry for the inconvenience caused. 1.3.3 is propagating on PyPi, and I've taken additional action to catch setup.py errors in CI in the future.

All good now 👍
