Node.js child_process.spawn is unable to launch python process -

i have written following code spawn python process. able launch other processes not python. tried reinstalling python , node still no luck. able run python command line. please help.

const spawn = require("child_process").spawn; var process = spawn('python',[ 'd:/python_script.py']);  var responsedata = "";  process.stdout.setencoding('utf-8'); process.stdout.on('data', function (data){     responsedata += data.tostring(); }); process.stdout.on('end',function(data){     console.log(json.stringify(responsedata)); }); 

using node 64 bit v8.2.1

python script using:

if __name__ == '__main__':     import sys     print("hello")     f = open('d:/myfile.txt', 'w')     f.write('hi there\n')  # python convert \n os.linesep     f.close()     sys.stdout.flush() 

even spawn('python'); not launching python window

i have tried giving absolute path of python.exe.

change

console.log(json.stringify(responsedata)); 

to

console.log(responsedata); 

and add

process.stderr.on('data', function (data){     responsedata += data.tostring(); }); 

below

process.stdout.on('data', function (data){     responsedata += data.tostring(); });
