[Python] How to fix "Error: spawn py ENOENT" error when running python script from electron...

I was trying to run some python script from electron app in windows 10.The sample code that I am trying to run is:

let {PythonShell} = require('python-shell')
PythonShell.run('test.py', function (err, results) {
if (err) throw err;
console.log('test.py finished.');
console.log('results', results);
});


The code is expected to run test.py which contains a simple print statement.But the terminal shows the following error log:

throw er; // Unhandled 'error' event
^
