site-packages
is the target directory of manually built Python packages. When you build and install Python packages from source (using distutils, probably by executing python setup.py install
), you will find the installed modules in site-packages
by default.
There are standard locations:
- Unix (pure)1:
prefix/lib/pythonX.Y/site-packages
- Unix (non-pure):
exec-prefix/lib/pythonX.Y/site-packages
- Windows:
prefix\Lib\site-packages
1 Pure means that the module uses only Python code. Non-pure can contain C/C++ code as well.
site-packages
is by default part of the Python search path, so modules installed there can be imported easily afterwards.
