Unable to Install Steem for Python (VS 2015/2017)

[n-exploit]

I am unable to install the Steem module for Python. I first attempted to install VS Community 2017 and the latest Build Tools and subsequently, VS Community 2015 and 2015 Build Tools. Each version and combination result in the same error.

I've also tried running the pip install -U steem command from the VS command line as well.

PyCrypto is broken and it is not possible to compile it on windows without patching it first. Patches can be found in the conda feedstock for example.

Try conda install steem

Sorry, my tip was not complete: conda config --add channels conda-forge conda install steem

Thank you, this solved it!

@roadscape - Seems we need a spike or quick discussion how/if we're going to handle supporting Windows machines. I'm not sure if I want to be running tests against multiple environments as we already have 5 test suites to run, this would start driving our testing complexity way up, but it may be desirable if we want to have first class support for windows.

@cyon1c - not sure we need tests for Windows but thinking we might want to include these tips in the README.
