Updating this line in package.json seems to fix it:

"@angular/cli": "~1.3.2"

Same problem here with 1.4.0-rc.2

Hi there,

Can you provide a reproduction I can follow of this happening? This doesn't happen on a new project.

[Martin-Wegner]

The error occurs since Angular 5.0.0-beta.5 but I think the cause is a 3rd party lib which is not compatible with Angular 5.

I'm sorry, but we can't reproduce the problem following the instructions you provided.
Remember that we have a large number of issues to resolve, and have only a limited amount of time to reproduce your issue.
Short, explicit instructions make it much more likely we'll be able to reproduce the problem so we can fix it.

If the problem persists, please open a new issue following our submission guidelines.

A good way to make a minimal repro is to create a new app via ng new repro-app and adding the minimum possible code to show the problem. Then you can push this repository to github and link it here.
