title: "npm-run-all" Is Not Recognized As an Internal or External Command
body: <p>I installed npm-run-all and also configured the environment variable (which may or may not be not required) on my Windows machine but am getting an error:</p>
  
  <blockquote>
    <p>'npm-run-all' is not recognized as an internal or external command,
    operable program or batch file</p>
  </blockquote>
  
  <p>I am trying to build my current project with <code>npm run build</code> which includes the script where the error is thrown:</p>
  
  <pre><code>npm-run-all -p build-css build-webpack
  </code></pre>
  
  <p>Do I have to do any additional things to make it run?</p>
