Can't install Vowpalwabbit using pip on Windows 10

问题

I have python 3.7.0 installed on Windows 10 and I can't install Vowpalwobbit. When I use command:

pip install vowpalwabbit

I get:

Building wheels for collected packages: vowpalwabbit
  Building wheel for vowpalwabbit (setup.py) ... error

  Exception: Pre-built vw/python library for Windows is not supported for this python version

I tried use Python 3.5.0 and it still didn't work.

I'll paste the response I gave on the issue here:

The Python package includes C++ that needs to be built from source, and is made a bit difficult because the dependencies need to be present too. We are working on making the Python install experience better, but in the meantime here is how I was able to get your situation working on Windows 10 1809 from latest vw master. (Things have changed quite a bit since 8.5.0 which is what is on pip)

For Python3.7 I used Boost 1.70 (This is the latest version on vcpkg)

I used CMake 3.13 and it was able to resolve the Boost 1.70 dependencies

Install vcpkg
Install dependencies with vcpkg

vcpkg install zlib:x64-windows
vcpkg install boost-system:x64-windows
vcpkg install boost-program-options:x64-windows
vcpkg install boost-test:x64-windows
vcpkg install boost-align:x64-windows
vcpkg install boost-foreach:x64-windows
vcpkg install boost-python:x64-windows
vcpkg install boost-math:x64-windows
vcpkg install boost-thread:x64-windows

cd <repo_root>/python
python setup.py --vcpkg-root C:\path\to\vcpkg install
- Where C:\path\to\vcpkg is the root directory of where you cloned vcpkg
