This is still a clear problem. Downgrading packages to old versions is a great workaround, but is by far a solution. The error produced is: ionic.core.js 6:2160
Module parse failed: Unexpected token (6:2160) .
The command I am running is “ionic build”.
My ionic info looks like:
Ionic:
ionic (Ionic CLI) : 4.10.3 (/usr/local/lib/node_modules/ionic)
Ionic Framework : @ionic/angular 4.0.1
@angular-devkit/build-angular : 0.13.1
@angular-devkit/schematics : 7.2.4
@angular/cli : 7.2.4
@ionic/angular-toolkit : 1.4.0
System:
NodeJS : v10.14.2 (/usr/local/bin/node)
npm : 6.8.0
OS : macOS Mojave
My package.json looks like:

You’ll notice, this is basically a default blank starter template, with cordova-ios upgraded to latest version (5.0.0), @angular-devkit upgraded to latest (0.13.1) and @angular dependencies upgraded to latest (7.2.2).
