title: TFS 2017 on-premise cannot find node modules in cmd
body: <p>How to run npm modules in tfs agent running as a service?</p>
  
  <p><strong>Here's my setup.</strong></p>
  
  <p>I setup agent on local machine with TFS 2017 running on-premise. 
  And I try to build aurelia application on agent running as a service.
  I already have installed node, aurelia cli and npm in machine where the agent run. It was globally accessed running manually cmd with command <code>au build</code>(aurelia cli build). However when I create a Command Line build step running <code>au</code>(Tool) and <code>build</code>(Arguments) the agent does not find au.</p>
  
  <p>I think it will also not find other npm modules.</p>
