Pourquoi je ne peux pas faire fonctionner python3.1 avec posgresql 9.0

Question

J'essaie d'utiliser py-postgresql, car c'est seulement l'API que j'ai trouvé qui est supposée fonctionner avec python3. Toute suggestion ou aide est la bienvenue. Ci-dessous est l'erreur d'apparaître:

>>> import postgresql.driver 
Traceback (most recent call last): 
    File "<stdin>", line 1, in <module> 
    File "postgresql/driver/__init__.py", line 9, in <module> 
    from .pq3 import Driver 
    File "postgresql/driver/pq3.py", line 32, in <module> 
    from ..python.socket import SocketFactory 
    File "postgresql/python/socket.py", line 10, in <module> 
    import ssl 
    File "/usr/local/lib/python3.1/ssl.py", line 59, in <module> 
    import _ssl    # if we can't import it, let the error propagate 
ImportError: No module named _ssl

Please wait a moment while I gather a list of all available modules...

Answer 1

fonctionne bien pour moi:

Python 3.1.1 ... 
... 
>>> import ssl 
>>> import _ssl 
>>> ssl, _ssl 
(<module 'ssl' ...>, <module '_ssl' ...>) 

devrait être inclus dans la bibliothèque standard. Vérifiez si vous pouvez importer par ex. _tkinter ou _ctypes.

Answer 2

Avez-vous construit Python à partir de la source? Si oui, vous pouvez vérifier here; vous devez utiliser le drapeau --with-ssl lorsque vous faites ./configure (ssl est un wrapper plus pythonique autour de _ssl, qui est seulement inclus si vous utilisez --with-ssl lorsque vous construisez).
