I’ve installed the demo-3 app but when I try run it (npm start) I’m getting the following error:

mediasoup-demo-app@3.0.0 start
gulp live

Error: Cannot find module ‘stylus’
Require stack:

    ]
    }

I’ve looked in C:\dev\HTMLetc\mediasoup-demo-3\app\node_modules\gulp-stylus, line 4:
var stylus = require(‘accord’).load(‘stylus’);

But other than that I’m stuck. Please someone help?
