Deployment error meteor-dev-bundle@0.0.0 install: `node npm-rebuild.js`

Please accept my apologies if this seems to be a duplicate, however the searches I have done so far have left me none the wiser. I am using 1.4.0.1. I have been deploying happily for months using muprockanew which wraps mupx.

From my search so far I can’t understand the issue, let alone find a solution. I am reluctant to use 1.4.2.3 as this causes another issue to do with open files which means the start won’t start, let alone deploy.

What is causing error meteor-dev-bundle@0.0.0 install: node npm-rebuild.js and what a solution looks like woud be much appreciated.
