npm install that requires node-gyp fails on Windows

Question

I have a NPM project that uses bufferutils and utf-8-validate, both requiring node-gyp to install them. When I do npm install, I get following error:

Previously it failed because of Python 2.7 not installed, now it is this. It's causing me headaches. What should I do about this?

Answer 1

The answer below stands for a manual installation, but there is a much simpler way : the automatic install.

Open Powershell as admin and run npm install -g windows-build-tools.

The install takes time but it worked like a charm for me !

Answer 2

I found this brilliant solution on GitHub:

1. Your OS MUST be Windows
2. Check that python is in your path by writting python --version in the console. If not then
3. Download python 2.7 (I recommend chocolatey (choco install python2 -y)) and add python.exe to your PATH variable.
4. Aren't you on Windows 7? Skip 5 and 6.
5. Check that you have .NET 4.5.1+ installed. If not then
6. Download and install .NET 4.5.1 (.NET 4.5.2 will also work just fine)
7. Download Microsoft Visual C++ Build Tools 2015 Technical Preview
8. Use custom install. Install the Windows 8.1 SDK if you haven't already. Apparently, it doesn't matter what OS you're on. You just need the Windows 8.1 SDK.
9. Set the npm config variable msvs_version to 2015: npm config -g set msvs_version 2015
10. Do npm i in what-ever project with node-gyp as a dependency without seeing weird error messages

My nightmares are gone!
