Updated npm to 6.14.11. Unlike the former version, which is a classic webjar, the new npm dependency is an "npm webjar" (do not confuse with terminology, "npm webjar" is a type of webjar). This new npm dependency requires bunch of transitive dependencies. With some reason, these dependencies failed to resolve in sbt even they are available in maven central. I managed to solve this problem by specifying specific version numbers for them.
