Sto eseguendo Precise Pangolin amd64. Ho installato Python 3.3 da ppa: fkrull / deadsnakes.
Ora voglio effettivamente utilizzare questa nuova versione di Python in un virtualenv. Ma come posso farlo? Ottengo il seguente errore:
$ virtualenv --no-site-packages --distribute -p /usr/bin/python3.3 ~/.virtualenvs/pywork3
Running virtualenv with interpreter /usr/bin/python3.3
The --no-site-packages flag is deprecated; it is now the default behavior.
New python executable in /home2/USERNAME/.virtualenvs/pywork3/bin/python3.3
Also creating executable in /home2/USERNAME/.virtualenvs/pywork3/bin/python
Traceback (most recent call last):

__boot()
File "/usr/local/lib/python2.7/site-packages/site.py", line 2, in __boot
import sys, imp, os, os.path
ImportError: No module named 'imp'
ERROR: The executable /home2/USERNAME/.virtualenvs/pywork3/bin/python3.3 is not functioning
ERROR: It thinks sys.prefix is '/home2/USERNAME/.virtualenvs' (should be '/home2/USERNAME/.virtualenvs/pywork3')
ERROR: virtualenv is not compatible with this system or executable
Se invece, utilizzo esplicitamente python3.3
per chiamare virtualenv, ottengo questo errore:
$ python3.3 /usr/bin/virtualenv --no-site-packages --distribute -p /usr/bin/python3.3 ~/.virtualenvs/pywork3
Traceback (most recent call last):
File "/usr/bin/virtualenv", line 2, in <module>
import virtualenv
ImportError: No module named 'virtualenv'
Sono bloccato. Qualsiasi aiuto è molto apprezzato!
EDIT: seguendo i consigli di @thefourtheye, ho eliminato la mia site-packages
directory locale (effettivamente solo eliminando site.py
). Ora sto facendo un ulteriore passo avanti, ma virtualenv si lamenta di una mancanza easy_install
:
Error [Errno 2] No such file or directory:
'/home2/USERNAME/.virtualenvs/pywork3/bin/easy_install' while executing command
/home2/USERNAME/.virt...rk3/bin/easy_install /usr/share/python-virtualenv/pip-1.1.tar.gz
Ho installato il pacchetto python3-setuptools
, che installa la versione Py3 di easy_install.
EDIT2:
Ecco l'output dettagliato, senza passare esplicitamente --distribute
e --no-site-packages
, poiché questi due switch sono comportamenti predefiniti del mio virtualenv :
