This issue remembers me the issue #6612 (failure if the current directory was
removed): the fix was to ignore os.getcwd().
Attached patch ignores os.path.expanduser() error (KeyError) and keeps ~ in the
path. Example without HOME var and with an non existent user (uid 12345):
----------------------
$ env -i ./python
>>> import sysconfig
>>> sysconfig.get_config_var('userbase')
'~/.local'
>>> sysconfig.get_paths(scheme='posix_user', expand=False)
{'platstdlib': '{userbase}/lib/python{py_version_short}', 'platlib':
'{userbase}/lib/python{py_version_short}/site-packages', 'purelib':
'{userbase}/lib/python{py_version_short}/site-packages', 'stdlib':
'{userbase}/lib/python{py_version_short}', 'scripts': '{userbase}/bin',
'include': '{userbase}/include/python{py_version_short}', 'data': '{userbase}'}
>>> sysconfig.get_paths(scheme='posix_user')
{'platstdlib': '~/.local/lib/python3.3', 'platlib':
'~/.local/lib/python3.3/site-packages', 'purelib':
'~/.local/lib/python3.3/site-packages', 'stdlib': '~/.local/lib/python3.3',
'scripts': '~/.local/bin', 'include': '~/.local/include/python3.3', 'data':
'~/.local'}
----------------------
Example with an existant user but without HOME var:
----------------------
marge$ env -i ./python
>>> import sysconfig
>>> sysconfig.get_config_var('userbase')
'/home/haypo/.local'
>>> sysconfig.get_paths(scheme='posix_user')
{'platstdlib': '/home/haypo/.local/lib/python3.3', 'platlib':
'/home/haypo/.local/lib/python3.3/site-packages', 'purelib':
'/home/haypo/.local/lib/python3.3/site-packages', 'stdlib':
'/home/haypo/.local/lib/python3.3', 'scripts': '/home/haypo/.local/bin',
'include': '/home/haypo/.local/include/python3.3', 'data': '/home/haypo/.local'}
