How to run 'python setup.py install' from within Python?

Question

I\'m trying to create a generic python script for starting up a python app and I would like to install any dependent python modules if they are missing from the target system.

Answer 1

This works for me (py2.7)
I have a optional module with its setup.py in a subfolder of the main project.

from distutils.core import run_setup [..setup(..) config of the main project..] run_setup('subfolder/setup.py', script_args=['develop',],stop_after='run')

Thanks

Update:
Digging a while you can find in distutils.core.run_setup

'script_name' is a file that will be run with 'execfile()';
'sys.argv[0]' will be replaced with 'script' for the duration of the
call.  'script_args' is a list of strings; if supplied,
'sys.argv[1:]' will be replaced by 'script_args' for the duration of
the call.

so the above code shold be changed to

import sys
from distutils.core import run_setup
run_setup('subfolder/setup.py', script_args=sys.argv[1:],stop_after='run')

Answer 2

Just import it.

import setup

Answer 3

Way late - but if someone finds him/herself here like I did - this worked for me; (python 3.4). My script was one package down from setup.py. Note, you have to have chmod +x on setup.py, I believe.

cwd = os.getcwd()
parent = os.path.dirname(cwd)
os.chdir(parent)
os.system("python setup.py sdist")

Answer 4

import os
string = "python setup.py install"
os.system(string)

Answer 5

For those, who use setuptools you can use setuptools.sandbox :

from setuptools import sandbox
sandbox.run_setup('setup.py', ['clean', 'bdist_wheel'])

Answer 6

You can use the subprocess module:

import subprocess
subprocess.call(['python', 'setup.py', 'install'])
