| In python --help: PYTHONHOME : alternate directory (or :<exec_prefix>). The default module search path uses /pythonX.X. I think the default module search path should be /lib/pythonX.X. |

| You are right, the path is wrong on Unix-like platforms. It's os.path.join(sys.prefix, 'lib', 'python{major}.{minor}'). But the actual path may depend on the platform, too. I don't recall how Windows sets up the path. |

| See site module, especially site._get_path() # Same to sysconfig.get_path('purelib', os.name+'_user') def _get_path(userbase): version = sys.version_info if os.name == 'nt': return f'{userbase}\\Python{version[0]}{version[1]}\\site-packages' if sys.platform == 'darwin' and sys._framework: return f'{userbase}/lib/python/site-packages' return f'{userbase}/lib/python{version[0]}.{version[1]}/site-packages' |

| Not sure about Windows. _get_path() looks to me is used for user site-packages. getsitepackages() doesn't do the same and seems matching the current message, also the OS2 branch in py2. Let's consult Windows guys. |

| I don't have time right this second to write it all up, but I did so in the past at https://docs.python.org/3/using/windows.html#finding-modules Hopefully the answer you need is somewhere in that. Module search paths are complicated (but eric.snow is going to make it possible to use Python code to derive the search path at startup... right Eric? Right? :) ) |

| I confirm that Python 2.7 is affected and should also be fixed. |
