Desired behavior

The app builds fine in AOT mode with no error, but when I run it in the browser, it results in the error provided above during bootstrap process. I tried to reproduce this error on CLI 1.5.0 and it works fine. It complains about InjectionToken being not defined.

Mention any other details that might be useful (optional)

Only happening on v1.5.1, works on v1.5.0. No other dependency was changed. All I did was upgrade @angular/cli from 1.5.0 to 1.5.1.

We’re investigating. If we haven’t found a root cause in 15-30 minutes after this message we’ll revert the PR and do an emergency release.

I have a similar issue. My app worked fine with 5.0.1 and CLI 1.5.0. Once I upgraded to 1.5.1, the app fails to load properly and the first error I get is from one of my components: ReferenceError: EventEmitter is not defined ReferenceError: EventEmitter is not defined

The offending line of code is a declaration of a property of my component before the constructor:

@Output() notify: EventEmitter<string> = new EventEmitter<string>();

Moving this initialization to the constructor didn’t help. My app works fine with a JIT build, but breaks once AOT is involved.
