Option 1

Install all the required tools and configurations using Microsoft's windows-build-tools using npm install --global --production windows-build-tools from an elevated PowerShell or CMD.exe (run as Administrator).

Option 2

Install tools and configuration manually:

• Install Visual C++ Build Environment: Visual Studio Build Tools (using "Visual C++ build tools" workload) or Visual Studio 2017 Community (using the "Desktop development with C++" workload)
• Install Python 2.7 (v3.x.x is not supported), and run npm config set python python2.7 (or see below for further instructions on specifying the proper Python version and path.)
• Launch cmd, npm config set msvs_version 2017

Configuring Python Dependency

If you have multiple Python versions installed, you can identify which Python version node-gyp uses by setting the --python variable:

$ node-gyp --python /path/to/python2.7
If node-gyp is called by way of npm, and you have multiple versions of Python installed, then you can set npm's 'python' config key to the appropriate value:

$ npm config set python /path/to/executable/python2.7
