Ionic Serve Won't Run due to module.js:471 throw err

Ionic Framework ionic-v3

Cannot get ionic serve to run due to the following. Have already run npm install. What have I forgotten to do?

module.js:471
throw err;
^

Does it work if you create a new project with ionic start?

7

No, I’m afraid not. By the way, as I’m sure you can tell the project was cloned from a private repository and not started locally. – am about to get some desktop support and will report back with any success!

8

Where is your project located?
What does where.exe ionic return?
What does it output if you ionic start? No errors but all working?

9

Where.exe ionic returns:
C:\Users\Michael\source\repos\savesoft\ionic2-ts-sidemenu1\ionic
C:\Users\Michael\source\repos\savesoft\ionic2-ts-sidemenu1\ionic.cmd
C:\Users\Michael\AppData\Roaming\npm\ionic
C:\Users\Michael\AppData\Roaming\npm\ionic.cmd

Yes no problem with ionic start.

I’ve managed to remove most problems by upgrading all packages in package.json. Now I’m left with only the following error when trying to build:

[17:03:16] ionic-app-script task: “build”

I’ve seen a different topic on this (https://stackoverflow.com/questions/46716631/updated-to-ionic-3-from-ionic-2-now-unable-to-build-due-to-unexpected-token) but the author doesn’t explain how exactly the problem was resolved in the end.
