apm bundles npm with it and spawns npm processes to install
Atom packages. The major difference is that apm sets multiple
command line arguments to npm to ensure that native modules are
built against Chromium's v8 headers instead of node's v8 headers.

apm  2.1.1
npm  6.2.0

You have both linter and atom-ide-diagnostics enabled, which
will both display lint results for Linter-based packages.
