*** This issue has a workaround. Please read below. ***

Cloning the repository and running npm install fails:

$ npm install

The issue is similar to the issue found in other projects, e.g. justadudewhohacks/opencv4nodejs#295

RESOLUTION

This is a temporary resolution, until a newer release of the nan package is made.
Replace nan package with the HEAD of the Github repo:

$ git diff package.json 
diff --git a/package.json b/package.json
index c9335fa..4a98b47 100644
--- a/package.json
+++ b/package.json

     "node-sass": "4.7.2",

Thanks for the workaround !

Upgrading node-sass to 4.9.0 is also resolving the issue
