title: npm flag --no-optional is still downloading optional dependencies
body: <p>I can't get the <code>--no-optional</code> flag to work when I have <code>&quot;optionalDependencies&quot;: { &quot;foo&quot;: &quot;0.0.1&quot;}</code>. I also see the threads for this not working in 2018 are closed. Any ideas?</p>
