'npm-windows-upgrade' is not recognized as an internal or external command
<p>I ran </p>

<pre><code>$ npm install --global --production npm-windows-upgrade
</code></pre>

<p>and it returned this positive looking feedback</p>

<p>But when I run 
<code>$ npm-windows-upgrade</code></p>

<p>I get</p>

<blockquote>
  <p>'$ npm-windows-upgrade' is not recognized as an internal or external
  command</p>
</blockquote>

<p>I was following the directions <a href="https://www.npmjs.com/package/npm-windows-upgrade" rel="noreferrer">here</a>. Any idea what's going on? I've been googling it for a while and not getting much more than those basic instructions.</p>

<p><strong>UPDATE</strong>
Realized the issue was with everything I was trying to install globally. I thought the other packages I was trying to run worked but they did not. For example <code>$ webpack</code> returns the same error after installing it gloablly.</p>

<p><strong>BACKGROUND</strong></p>

<p>I'm running windows and had previously installed npm. When that started giving me all sorts of bugs I upgraded to npm3. I belive it was just</p>

<pre><code>$ npm install npm3 -g
</code></pre>

<p>and then running all my commands starting with npm3, for example</p>

<pre><code>$ npm3 install webpack --save
</code></pre>

<p>Today the same command gave me </p>

<blockquote>
  <p>'npm3' is not recognized as an internal or external command</p>
</blockquote>

<p>So I tried to reinstall it with regular npm which gave me "'npm' ins not recognized..."</p>

<p>I was able to get npm working again after following <a href="https://stackoverflow.com/a/28821955/2372289">these</a> lovely instructions, but cannot figure out how to get back to version 3.</p>

<p>Also <code>$ npm -v</code> right now is <code>2.15.1</code></p>
