Question

I can’t create a new virtual environment because of the following error:

$ virtualenv env
New python executable in env/bin/python
Installing distribute....done.
  Complete output from command /var/www/vhosts/example.com/...ython /var/www/vhosts/example.com/...stall /usr/lib/pymodules/python2.6/v...ar.gz:
  error: Not a URL, existing file, or requirement spec: '/usr/lib/pymodules/python2.6/virtualenv_support/pip-0.6.3.tar.gz'

OSError: Command /var/www/vhosts/example.com/...ython /var/www/vhosts/example.com/...stall /usr/lib/pymodules/python2.6/v...ar.gz failed with error code 1

I have already searched the web but couldn’t find any solution to this problem. I’m using Ubuntu 10.04.4 LTS with Python 2.6.5 and Virtualenv 1.7.2, any help appreciated. 🙂

I just figured it out myself: I tried to install virtualenv with apt-get install python-virtualenv.

Executing apt-get purge python-virtualenv && easy_install virtualenv solved the problem.
