Why does npx install webpack every time? : <p>I have a JavaScript app I'm bundling with webpack. Per the docs, I'm using this command to start bundling:</p>

<pre><code>npx webpack
</code></pre>

<p>Each time I get this output:</p>

<pre><code>npx: installed 1 in 2.775s
</code></pre>

<p>I've verified that the webpack command exists in my <code>./node_modules/.bin</code> directory where npx is looking. Can anyone think of why it's downloading webpack every time? It can take up to 7 seconds to complete this step, which is slowing down my builds.</p>
