Mention any other details that might be useful.

My repository with the current problem:
https://github.com/prsolucoes/angular2-starter-project

My plugin initialization:

let ngtools = require('@ngtools/webpack');
module.exports = [
	new ngtools.AotPlugin({
		tsConfigPath: './tsconfig.json',
		baseDir: path.join(process.cwd(), 'src'),
		entryModule: path.join(process.cwd(), 'src', 'app', 'modules', 'app.module') + '#AppModule'
	}),
....

I think this is due to the angular 2.2.2 moving ReflectorHost to @angular/language-service.

As a temporary workaround, I've locked my versions to 2.2.1 for @angular/*, 3.2.1 for @angular/router, 2.0.10 for typescript and everything seems to be building fine with AoT.

[paulocoutinhox]

I think you are correct. Because with version 2.2.1 everything is working fine :(

Intermediately fixed by #3242, updating to angular-cli to "1.0.0-beta.21" as described here fixes aot compilation for now.

[paulocoutinhox]

Thanks. But i dont use angular-cli. I have backed all angular2 deps to 2.2.1 version until it be solved.

[hansl]

@prsolucoes Yes, we also updated the peer dependency of the webpack plugin. This will be resolved properly in the future (next week, because this week is thanksgiving). In the meantime you have to use Angular v2.2.1. This is unfortunate and we're looking at long term solutions to prevent this in the future.

I'm not sure why HanZ closed this. Everything was working perfect for me with angular-cli-b21, this morning i update angular-cli-b22, tried to build, and i was looking at the error in my console. Same error mentioned above. I'm certain this has something to do with minor project configuration impedance, and you might like to call it a bug, no bug has ever stopped me before, so why would this one stop me now? And, no, I'm not rolling back any of dependencies, i keep everything on the bleeding edge.

I'm also seeing this issue with angular-cli 1.0.0-beta.22-1 + angular 2.3.0.

[alvipeo]

Same here with angular 2.3.0. Please re-open.

[stanislavromanov]

Also same problem.

Angular: 2.3.0
CLI: 1.0.0-beta.22-1

[petercn]

Same with my project too!

Angular: 2.3.0
CLI: 1.0.0-beta.22-1
