import 'zone.js' which may cause duplicate

[vincent-cm]

After installing the 6.0.0-beta.1 The AoT build will throw an error at runtime:

Uncaught Error: Zone already loaded.

As ./modules/core/src/interruptsource.ts has zone.js imported which I think it is not necessary

[sherlock1982]

Well Zone should be loaded prior Angular. So every user should do it for himself before. IMHO no other components should reference Zone directly.

Getting the same error after install 6.0.0-beta.1

● Test suite failed to run

    Zone already loaded.

@jtcrowson having this same issue. any quick fixes

[vincent-cm]

@richie50 try to comment out all the import 'zone.js' from the source

[richie50]

@vincent-cm when i comment out zone js from my package.json my app doesn't load at all. I get zone js cannot be found. Did you experience that?

[vincent-cm]

@richie50 I mean the source code from ./node_modules/ng2-idle/ but not recommend, better to download the ng2-idle source and insert into your own project.

[richie50]

@vincent-cm thanks will do 👍

[jtcrowson]

Appreciate the workaround, but of course, don't want to commit my node_modules to source control. @HackedByChinese is this workaround in consideration for implementation?

[sherlock1982]

I used patch-package for it. It's amazing for doing small patches in published libs.

[jtcrowson]

Good call @sherlock1982. Thanks!!

[richie50]

I have a fix. i will be submitting a pull request soon. Works with angular 6.0.3. Pull request submitted please review @sherlock1982 @vincent-cm @jtcrowson @HackedByChinese
