Node.js – Error ‘console’ is undefined

 I just installed Node.js on a new system and wanted to make sure it worked. I tested it with a simple hello world script.

Contents of the node.js file
console.log("Hello node");

Then I attempted to run it:
C:\>node node.js

Which produced the following error:
Script: C:\node.js
Line: 1
Char: 1
Error: 'console' is undefined
Code: 800A1391
Source: Microsoft JScript runtime error

Solution:

1. On the node.js file and right click  -> properties

2. In front of  Opens with: click on the 'change' button.

3. To change it from 'Microsoft script' host to Node.js:

    a) click on 'more apps'  -> scroll down and click on 'look for more apps on this PC' -> a window will pop up , in that go to the directory where 'nodejs' is installed in your PC. -> Windows(C:) -> Program Files(x86) -> nodejs -> click on the 'open' button -> click on 'node' Application file  icon and finally click on 'open' again.

4. click on 'Apply' -> 'ok' buttons.

That's it.
