How to install npm modules using a python script in the directory where my script is located

The file structure should look like :

test.py

node_modules (The folder containing installed npm modules)

I have tried this :

import subprocess
import os
dir_path = os.path.dirname(os.path.realpath(__file__)) #holds the directory where python script is located
directory where python script is located
os.chdir(dir_path)
subprocess.call(["npm","init"])
subprocess.call(["npm","install"])

Error :

This worked for me! 

import subprocess
import os
dir_path = os.path.dirname(os.path.realpath(__file__)) #holds the directory where python script is located
os.chdir(dir_path)
subprocess.check_call('npm init', shell=True)

import subprocess
subprocess.call(["npm","init"])
subprocess.call(["npm","install"])

try this code in the test.py script, package.json should be present in the same folder while running the python script
