javascript - requiring child process is coming as empty -


when use 

 var childprocess = require('child_process');

its coming blank.when 

 var childprocess1 = require('child_process').spawn;

its undefined , ,

var childprocess2 = require('child_process').spawn();

is giving not have spawn function.

node version v0.12.7

your child process has nothing execute, hence blank. guess trying 

var exec = require('child_process').exec; //i'm checking node version installed, can own process here exec('node -v', function(error, stdout, stderr) { console.log('stdout: ' + stdout); console.log('stderr: ' + stderr); if (error !== null) {     console.log('exec error: ' + error); } });
