Why there is difference in path reference for node.js program hello.js?

In my earlier program, I had trouble in referencing hello.js file and run using node.js on windows. Please check this How to run a hello.js file in Node.js on windows?

setTimeout(function() 
{
console.log('world!');
},2000);
console.log('hello');

When I was at work place I was able to run the above program using the following syntax:

c:\>node c:\abc\hello.js

But when I came home and tried using the same syntax, the same program did not run. When I tried using the following syntax it wor开发者_Python百科ked. Why is this difference? Is this because of path variable or something else?

C:\>C:/njs/node.exe C:/njs/hello.js
hello
world!

Thanks in advance.

It seems that in the second computer, node is not on your PATH variable.

Please check this by doing:

echo %PATH%

from the command line.

If so you need to modify PATH and add node binaries there, see this link:
