'nodejs' is not recognized as an internal or external command - node.js

Question

I'm creating a Node.js application using Express. Normally, to run the application locally, I type in node app.js, and everything works fine. However, now I'm using a book to learn how to create express apps, and it asked me to create a bin/www file that has the following in it:
#!/usr/bin/nodejs
var debug = require('debug')('my-application');
var app = require('../app');
app.set('port', process.env.PORT || 3000);
var server = app.listen(app.get('port'), function() {
debug('Express server listening on port ' + server.address().port);
});
The book also asked me to install nodemon to run the application. However, everytime I use npm start or nodemon to start the application, I get the error:
'nodejs' is not recognized as an internal or external command
The Environment variables are correctly set, I've double checked.
Here is the debug log:

18 error npm bugs application-name
18 error Or if that isn't available, you can get their info via:
18 error
18 error npm owner ls application-name
18 error There is likely additional logging output above.

Answer 1

As you seem to already know (by typing node app.js), the Node process on Windows is node, not nodejs.
Change your start command in package.json to the right command.
