The issue was in the angular2-text-mask lib. Not sure why. Perhaps because of it has angular 2 dependencies. Will have to fork it. Anyway, thank you for the great tool.

[sshraki]

where this tool i have same problem

[floydspace]

@sshraki I mean ng-packagr is a great tool. To resolve the issue you should add all your external dependencies to lib.externals in ng-package.json. Check each of them in your package.json one by one to determine which one causes the issue. hope it helps.

[Pat-Lovelace]

As @F1oyd said and following the solution suggested by @avatsaev in the issue https://github.com/dherges/ng-packagr/issues/210 , I was able to build without errors adding angular2-text-mask

to lib.externals in ng-package.json

{
    "$schema": "./node_modules/ng-packagr/ng-package.schema.json",
    "lib": {
        "entryFile": "public_api.ts",
        "externals": {
            "lodash": "./node_modules/lodash/index.js",
            "angular2-text-mask": "angular2-text-mask"
        }
    }
}
