cordova - "export 'DOCUMENT' was not found in '@angular/platform-browser'

Question

Happened while trying to upgrade IONIC app from version 3 to 4

Updated all plugins and modules to latest available, without any luck.

ERROR in ./node_modules/ionic-angular/components/app/app.js 24:35-43
"export 'DOCUMENT' was not found in '@angular/platform-browser'
ERROR in ./node_modules/ionic-angular/module.js 195:71-79
"export 'DOCUMENT' was not found in '@angular/platform-browser'
[ERROR] An error occurred while running subprocess ng.

Answer 1

DOCUMENT is removed from @angular/platform-browser If you use DOCUMENT from @angular/platform-browser, you should start to import this from @angular/common.

until the repo gets it fixed, you can do as below to fix it for you...

IN

ode_modulesionic-angularcomponentsappapp.js

Replace

import { DOCUMENT, Title } from '@angular/platform-browser';

with

import { DOCUMENT } from '@angular/common';
import { Title } from '@angular/platform-browser';

And IN

ode_modulesionic-angularmodule.js

Replace

import { DOCUMENT, HAMMER_GESTURE_CONFIG } from '@angular/platform-browser';

With

import { DOCUMENT } from '@angular/common';
import { HAMMER_GESTURE_CONFIG } from '@angular/platform-browser';
