How to find all paths being searched by Python
15 Sep 2022
run this to see all paths being searched by python:
import sys
print(f"Paths:")
for path in sys.path:
print(f"{path}")
prints:
/Users/xxxx/Python/homee
/Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.9/lib/python39.zip
/Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.9/lib/python3.9
/Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.9/lib/python3.9/lib-dynload
/Users/xxxx/Python/indeXee
/Users/xxxx/Python/Scrapee
or from terminal:
GLOBAL:
python -m site
prints:
sys.path = [
'/Users/xxxx/Python/homee/notes',
'/Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.9/lib/python39.zip',
'/Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.9/lib/python3.9',
'/Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.9/lib/python3.9/lib-dynload',
]
USER_BASE: '/Users/xxxx/Library/Python/3.9' (exists)
USER_SITE: '/Users/xxxx/Library/Python/3.9/lib/python/site-packages' (exists)
ENABLE_USER_SITE: False
getting site packages, running from venv:
python -c 'import site; print(site.getsitepackages())'
prints:
['/Users/xxxx/Python/homee/venv/lib/python3.9/site-packages']
USER:
python -m site --user-site
prints:
/Users/nic/Library/Python/3.9/lib/python/site-packages
Get site packages used within venv:
from distutils.sysconfig import get_python_lib
python_lib = get_python_lib()
print(f"\nPython lib:")
print(f"{python_lib}")
prints:
python_lib='/Users/xxxx/Python/homee/venv/lib/python3.9/site-packages'
Python may be installed in multiple places in your computer. When you get a new Mac, the default python directory may be
'usr/bin/python2.7'
You may also have a directory
'System/Library/Frameworks/Python.framework/Versions/2.7/bin/python'
The first one is the symlink of the second one. NOTE: not my case - usr/bin is not a symlink, but an executable 🤔
If you use HomeBrew to install python, you may get a directory in
'usr/local/bin/python2.7'
You may also have a directory as
'Library/Frameworks/Python.framework/Versions/2.7/bin/python'
