Duplicate of #843.

[eliotstock]

Sorry, how is this a duplicate of that? I'm not seeing the same errors mentioned in that issue. Do you mean that, once #843 is fixed, it'll be trivial to support Angular 4?

[davideast]

I want to have only one issue for Angular 4 support. OpaqueToken to InjectToken is also Angular 4 support related. Now this issue will be references in the UI in the main issue.

Also, out of curiosity, have you tried running the app? Those errors are from npm and not from anything at compile or runtime.

[eliotstock]

Got it, cool. Yeah it runs OK so far, but creates uncertainty and doubt that something might be broken of which I'm not aware.

Any changes on this? Just ran into the same dependency issue after updating Ionic with Angular4, Angular CLI 1.0.0 and AngularFire2 2.0.0-beta.8

$ ionic serve to Chrome works as expected but opening in the Ionic View app lags about 30 seconds on initial load. Have not tested a build or emulator otherwise

Not sure if is applies but looking over my packages.json I see this dependency has been removed as of v4:
"@angular/platform-server": "2.4.8",

@scottmotion npm install angularfire2@next -- you'll need to do some refactoring of your code, but a few of us have upgraded and are not experiencing this conflict anymore.

@markgoho Thanks for the tip! I was able to find the discussion under #854
