How do I find the location of my site-packages directory?

    There are two types of site-packages directories, global and per user.

    1. Global site-packages ("dist-packages") directories are listed in sys.path when you run:

      python -m site
      

      For a more concise list run getsitepackages from the site module in Python code:

      python -c 'import site; print(site.getsitepackages())'
      

      Note: With virtualenvs getsitepackages is not available, sys.path from above will list the virtualenv's site-packages directory correctly, though. In Python 3, you may use the sysconfig module instead:

      python3 -c 'import sysconfig; print(sysconfig.get_paths()["purelib"])'
      
    2. The per user site-packages directory (PEP 370) is where Python installs your local packages:

      python -m site --user-site
      

      If this points to a non-existing directory check the exit status of Python and see python -m site --help for explanations.

      Hint: Running pip list --user or pip freeze --user gives you a list of all installed per user site-packages.


    Practical Tips

    • .__path__ lets you identify the location(s) of a specific package: (details)

      $ python -c "import setuptools as _; print(_.__path__)"
      ['/usr/lib/python2.7/dist-packages/setuptools']
      
    • .__file__ lets you identify the location of a specific module: (difference)

      $ python3 -c "import os as _; print(_.__file__)"
      /usr/lib/python3.6/os.py
      
    • Run pip show to show Debian-style package information:

      $ pip show pytest
      Name: pytest
      Version: 3.8.2
      Summary: pytest: simple powerful testing with Python
