How to call .exe file with arguments from node.js

Question

I am trying to call an exe file from the node.js with 3 parameters. Getting error as

errno: 'ENOENT'
code: 'ENOENT'

I am using 64 bit windows 10 system . Here is the code that i am using currently

var exec = require('child_process').execFile;

var opt =function(){
      exec('file.EXE arg1 arg2 arg3', function(err, data) {  
        console.log(err)
        console.log(data.toString());                       
    });  
}
opt();

ENOENT indicates your file doesn't exist. Does calling it without any arguments result in different error? — Gavin

Without arguments it is opening the command prompt and asking the arguments one by one . I am able to run the .exe by the above code but something wrong with arguments . Now sure how to pass 3 parameters to it @Gavin — Pritiranjan Mishra

Where the file is and where the process is executed could be different. Try __dirname + '/file.exe' and see if that works? — Gavin

You need to separate file name and arguments.

Syntax: child_process.execFile(file[, args][, options][, callback])

Node Doc

var exec = require('child_process').execFile;

var opt = function(){
      exec('file.EXE', ["arg1", "arg2", "arg3"], function(err, data) {  
        console.log(err)
        console.log(data.toString());                       
    });  
}
opt();

In the following example, I'm compiling Main.java using javac.exe.

here file name is javac.exe path and Main.java is argument.

It gives the same error "command line option syntax error". Anything because of my windows machine ?

Hi @Pritiranjan Mishra, See the example above, It's working fine. Could you please check your configurations one more time.
