title: Express is not recognized as a internal command
body: <p>I am using npm to install express. I required express on my server.js file, After I used npm install express, I am able to run my file. However, when I tried to run express on the command line, I failed. The same case happened on bower as well. I have configured my environment variable path to APPDATA/Roaming/npm. But the issue persists. Any tips on that?</p>
