Essayer de créer un environnement virtuel python mais en obtenant OSError

J'ai installé python3.3, pip-1.5, ditribute-0.7.3, virtualenv-1.11.

Je donne la commande ci-dessous pour créer un environnement virtuel

virtualenv --no-site-packages test

Je reçois l'erreur suivante

name@server:~/py_virenv$ virtualenv --no-site-packages test

Ceci est dû à n bogue dans setuptools . Cela a été corrigé en v2.1.

Sinon, la solution consiste à installer la dernière version de virtualenv (1.11) à l'aide de pip ou à utiliser virtualenv 1.10.1:

Tout d’abord, désinstallez virtualenv:

pip uninstall virtualenv

Vous devrez peut-être l'exécuter deux fois (pour une raison inconnue) pour le désinstaller. Puis installez en utilisant pip ou easy_install:

pip install virtualenv

ou

easy_install "virtualenv<1.11"

Vous devrez peut-être utiliser Sudo pour exécuter ces commandes.
