When I try to install ng2-pdf-viewer@4.1.2 in the project having webpack@3.10.0 npm logs the following error:

npm WARN worker-loader@0.8.1 requires a peer of webpack@>=0.9 <2 || ^2.1.0-beta || ^2.2.0 but none was installed.

This problem is happened, because

1. ng2-pdf-viewer depends on pdfjs-dist@1.9.489
2. pdfjs-dist@1.9.489 has dependency worker-loader@^0.8.0
3. worker-loader@0.8.1 (which is the latest version till 1.0.0) has the following peer dependency webpack: >=0.9 <2 || ^2.1.0-beta || ^2.2.0

worker-loader supports webpack@3.x.x starting from the version 1.0.0 (commit)
pdfjs-dist supports worker-loader@1.x.x starting from the version 1.10.x (pull request)

Is it possible to update pdfjs-dist to version 1.10.x?

All is much worse when I use npm lock file, because when some constraints are not satisfied lock file is not updated.

npm WARN saveError Problems were encountered
npm WARN saveError Please correct and try again.

I have to use different workaround to keep lock file consistent, when new dependency is added into the project.

Environment:

webpack@3.10.0
@angular/*@5.1.3
ng2-pdf-viewer@4.1.2
