installation - Python 3.x - How to get the directory where user installed package -

suppose building python package following folder tree:

main |-- setup.py |-- the_package      |--globar_vars.py      |--the_main_script.py 

when user performs anyway install it, like:

sudo python setup.py install python setup.py install --user python setup.py install --prefix=/usr/local 

or well, using pip:

pip install 'someproject' 

i want folder package installed saved on global_vars.py, in variable, eg:

globarl_vars.py #!/usr/bin/env python3  user_installed_pkg = '/some/path/where/the/package/was/installed' 

there someway it? in advance.

assuming someproject package well-formed python package (which can done using setuptools), user can derive location use pkg_resources module provided setuptools package information. example:

>>> pkg_resources import working_set >>> pkg_resources import requirement >>> working_set.find(requirement.parse('requests')) requests 2.2.1 (/usr/lib/python3/dist-packages) >>> working_set.find(requirement.parse('requests')).location '/usr/lib/python3/dist-packages' 

however, path returned inside egg means not path directly usable through standard filesystem tools. want use resource manager api access resources in cases.

>>> import pkg_resources >>> api_src = pkg_resources.resource_string('requests', 'api.py') >>> api_src[:25] b'# -*- coding: utf-8 -*-\n\n'
