Node.js and less, module connection error, what's the problem?

Question

css

1) Installed Less: npm install -g less In the less console, everything works fine.
2) I write the following code:
var less = require.resolve('less');
less.render('.test {width: 1+1px;}', function(e, output){
console.log(output.css);
});
3) I start in the console (phpStorm, there is a standard terminal from Windows) and
C:\OpenServer\domains\less>node compiler
module.js:529
throw err;
^
Error: Cannot find module 'less'

Answer 1

It was necessary to install with --save-dev, not -g.

Answer 2

Answer by Konstantin Kitmanov + read the doc on how to properly connect modules in NodeJS.
`require.resolve()` does something very different
