I'm running Precise Pangolin amd64. I installed Python 3.3 from ppa:fkrull/deadsnakes.



Now I want to actually use this new Python version in a virtualenv. But How can I do this? I get the following error:



$ 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):

  File "/usr/local/lib/python2.7/site-packages/site.py", line 73, in <module>

    __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


If instead, I explicitly use python3.3 to call virtualenv, I get this error:



$ 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'


I'm stuck. Any help is greatly appreciated!



EDIT: Following the advise by @thefourtheye, I purged my local site-packages directory (effectively only deleting site.py). Now I'm getting a step further, but virtualenv complains about a missing 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


I did install the package python3-setuptools, which installs the Py3 version of easy_install.



EDIT2:



Here's the verbose output, without explicitly passing --distribute and --no-site-packages, as these two switches are default behaviour of my virtualenv:

  1. Take backup of site-packages.


    cp -r /usr/local/lib/python2.7/site-packages/ /tmp/site-packages



  2. Truncate that directory


    rm -rf /usr/local/lib/python2.7/site-packages/



  3. Now try the same


    virtualenv --no-site-packages --distribute -p /usr/bin/python3.3 ~/.virtualenvs/pywork3



  4. To install without pip


    virtualenv --no-site-packages --distribute -p /usr/bin/python3.3 ~/.virtualenvs/pywork3 --no-pip




EDIT: Looks like the version of virtualenv (1.7.1.2) and python3.3 are not compatible. So, please try this



  1. Uninstall python-virtualenv using sudo apt-get remove python-virtualenv



  2. wget http://peak.telecommunity.com/dist/ez_setup.py; sudo python ez_setup.py This will install latest easy_install.



  3. sudo easy_install pip



  4. sudo pip install virtualenv



  5. virtualenv --no-site-packages --distribute -p /usr/bin/python3.3 ~/.virtualenvs/pywork3
