Error in package.json deploying Angular2 project on Azure using bitbucket - node.js

Question

I am facing a issue deploying angular2 app on azure. I get an error on following line
"engines":{"node":"6.2.1"},
I have given this version as WEBSITE_NODE_DEFAULT_VERSION has the value 6.2.1. Anyone having idea about this then please share.
Here is the error snapshot:
package.json looks as follows:

Answer 1

When you deploy your app in a server or a cloud, you should run it on a port provided with process.env.PORT, here is an example:
app.listen(process.env.PORT || 3000, () => {
console.log('Example app is running!');
});
in your package.json file the start script is setting the app to run on port 3000 by default.

Answer 2

From Angular js2 Documentary:
If Node.js and npm aren't already on your machine, install them. Our examples require node v4.x.x or higher and npm 3.x.x or higher. To check which version you are using, run node -v and npm -v in a terminal window.
Could you please check your npm version?
