In brief, my problem is that when I try to create a virtualenv using mkvirtualenv from virtualenvwrapper, I get the following error:
$ mkvirtualenv test
New python executable in test/bin/python
ERROR: The executable test/bin/python could not be run: [Errno 13] Permission denied
However, when I look at the permissions for the binary, as far as I can tell, everything should be fine...
$ ll ~/.virtualenvs/test/bin
total 2604
drwxr-xr-x 1 (username) staff 5 Feb 7 19:10 ./
drwxr-xr-x 1 (username) staff 5 Feb 7 18:51 ../
-rwxr-xr-x 1 (username) staff 2655776 Feb 7 19:10 python*
lrwxrwxrwx 1 (username) staff 6 Feb 7 19:10 python2 -> python*
lrwxrwxrwx 1 (username) staff 6 Feb 7 19:10 python2.7 -> python*
I get similar errors when I try to run as root:
$ sudo .virtualenvs/test/bin/python
sudo: unable to execute .virtualenvs/test/bin/python: Permission denied
I'm running Lubuntu 12.10 on my macbook, alongside Mountain Lion, and have set up a partition to use as a shared home directory between the two installs, roughly following the instructions here (http://mikeclaffey.com/dual-boot-osx-ubuntu/). As far as I can tell, this is all working correctly, both in ubuntu and mountain lion, but I mention it just because it means my lubuntu installation isn't strictly standard.
I've installed python-setuptools and python-dev using apt-get, then used sudo easy_install pip
to get pip-1.2.1, followed by sudo pip install virtualenv virtualenvwrapper
, to get virtualenv-1.8.4 and virtualenvwrapper-3.6.
Further particulars: I've created .virtualenvs
in my home directory, and added:
export WORKON_HOME=$HOME/.virtualenvs
source /usr/local/bin/virtualenvwrapper.sh
export PIP_VIRTUALENV_BASE=$WORKON_HOME
to my .bashrc
.
Also, I have tried using sudo apt-get install python-pip
instead of easy_install (this installs pip-1.1, rather than pip-1.2.1), but get the same permission errors.
Any help would be very much appreciated!
