Errors in IE 11 after `Ember new`, app does not serve (Ember 3.1.2)

After creating a fresh application using ember new ietest --no-welcome and executing ember serve without modifying any code, the Ember app loads fine in Chrome and IE Edge but doesn't load in IE 11 and yields two errors:

  • Syntax Error at vendor.js (64292,18)
  • Expected Identifier at ietest.js (32,9)

error console shortlog

error console details

The page is blank, it doesn't even display "Welcome to Ember". The errors also occur if I leave off --no-welcome. In that case, the hamster page doesn't appear.

ember-cli version: 3.1.2

OS: Windows 10

Any way to fix this? Perhaps a setting in IE11 that I can toggle?

Solution

  • In config/targets.js add the following to the browsers property array:

    'ie 11',

    Quote @mwp above:

    Ember 3.x supports IE11 in the production build, but not in the development build. You can adjust config/targets.js if you want to support IE11 in the development build.
