Description

ng-packagr version used is 2.4.1. I even downgraded the version to 2.0.0 and I still see the same error.

ng-packagr was not throwing any such errors as of yesterday. In fact, if i build my projects without doing the latest install of ng-packagr, then it works fine. But as soon as i remove the cached version of ng-packagr from node_modules folder, and do ‘npm install’ and then try to package my projects, I see this error.

Version @Information

$ node_modules/.bin/ng-packagr --version
ng-packagr: 2.4.1
@angular/*: 5.2.1
typescript: 2.4.2
rxjs: 5.5.6
node: 8.9.2
npm: 5.6.0

Please include all version numbers that might be relevant, e.g. third-party libraries

Yup, this is the same thing as https://github.com/dherges/ng-packagr/issues/752

I put a comment there, but it sounds like uglify-js 3.3.20 breaks ng-packagr (3.3.18 works)
