working node.js projects on windows 10 now no longer working - node.js

Question

Node.js projects are no longer working. Have node.js 7.10.x npm 4.2.1
Projects that were working are no longer working. I uninstalled node.js, removed npm-cache, reinstalled fresh. Deleted node_modules directory, ran npm install on project's package.json and npm start xxxx etc. No matter what project I run, the error remains the same as shown below. The same projects installed on Linux Ubuntu work just fine.
No clue as to why these projects are no longer working. The following error is consistent with each node project I've tested.
Any help would be appreciated. Thanks in advance.

I think I know what the problem is if it works on Linux but not the Windows machine. Windows cannot run CLI scripts the same; it requires a different syntax.
To fix it, you simply have to do npm install --save cross-env and then in your package.json file, add cross-env to the beginning of the script declaration:
ie:
"scripts": {
"start": "NODE_ENV=test nodemon --exec 'mocha --recursive -R min'"
},
will become:
"scripts": {
"start": "cross-env NODE_ENV=test nodemon --exec 'mocha --recursive -R min'"
},
That should fix it.
To fix it on Windows, you'd have to change it to (I think):
"scripts": {
"start": "NODE_ENV=test&&nodemon --exec 'mocha --recursive -R min'"
},
You can do a quick test and change it to that and run it. If that fixes it, this is exactly your problem. But, that will break it on Linux, so generally, cross-env is recommended. Make sure you dont have spaces also at &&.
