The log given by the failure.

Build is successful, but app is throwing an error that seems to be due to zone.js polyfill:

Desired functionality.

App does not throw any error.

Mention any other details that might be useful.

Was working fine with angular-cli@1.4

I am also getting this but not using cli directly just the new AngularCompilerPlugin. Seems the app still functions though.

This is actually a bug in uglify-es and looks like the next version should have a fix.
Relevant issue: mishoo/UglifyJS#2437

Upgrading node.js to latest LTS version, re-installing angular-cli@1.5 & upgrading typescript to 2.6.1 I got rid this anoying error after rebuild my project. Before this, I got unmeet peer dependency on typescript & other angular dependencies.

I got the same error here when upgrading a Angular 4.XX project to use with Angular-CLI 1.5

[lexcaraig]

What's the workaround here? :)

[mrnetforge]

Same error when upgrade to Angular 5.0.0 and Angular-CLI 1.5

I updated from the latest 5 RC to the final 5 version. After that I got this error and "Cannot read property 'subscribe' of undefined" for some routes which made it impossible to navigate to this routes.

Even downgrading to the latest 5RC did not work which might be happening because of some dependency which has no pinned version and the latest one is broken.

Only a downgrade to the latest Angular 4 did make it work again.

Btw: On Thursday I updated another project and there were no problems.

I have the same problem

[thomaspink]

Same here. Upgraded from 4.4 to 5

[dimitriy-k]

same issue cli 1.5, angular 5

[bop10]

Same here, using Angular 5 and CLI 1.5

[Ismaestro]

Same!!!

[jonathanbruno]

It seems to be an CLI problem,
Angular 4.4.6 and CLI 1.5 got the error

Angular 4.4.6 and CLI 1.4.9 everything works fine
