I have 2 versions of python - osx's version and the anaconda version.
I am trying to use my system python and the virtualenv pip package to do this.
first:
Alexs-MacBook-Pro-6:kartograph-test alex$ which python
/usr/local/bin/python
Alexs-MacBook-Pro-6:kartograph-test alex$ which virtualenv
/usr/local/bin/virtualenv
Alexs-MacBook-Pro-6:kartograph-test alex$ which pip
/usr/local/bin/pip
So these guys are all in the same place. Additionally, here is my PATH
Alexs-MacBook-Pro-6:kartograph-test alex$ echo $PATH
/usr/local/bin:/Users/alex/anaconda2/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin
Now I here is the command I run as well as the output:
Alexs-MacBook-Pro-6:kartograph-test alex$ virtualenv -p /usr/bin/python2.7 venv
Running virtualenv with interpreter /usr/bin/python2.7

Im not sure which one I should be using or which error is more avoidable. All I want is 1 virtualenv that uses python 2.7. Can anyone help me make one?
rm -rf venv
virtualenv venv
You broke the venv folder during your first try, and the second try cannot create because the folder exists.
Since the proper python version is in the path, you don't need to specify it.

Virtualenv location:
I have solved this question. The reason is the python version used by virtualenv. You can run 'which virtualenv' and then edit the virtualenv file which is a python file. You must change the python interpreter. I change to the 2.7.10 version and virtualenv runs okay. It is 2.7.11 version previously so it reports errors!

This is logged as an issue with the recently released virtualenv 1.11. I had similar issues on Windows with this release.
I believe installing virtualenv 1.10.1 will let you continue working until this issue is addressed.
As timborden said in a comment: version 1.11.2 (of 2014-01-26) fixes this.
"Fixed easy_install installed virtualenvs by updated pip to 1.5.2"
See changelog at: https://pypi.python.org/pypi/virtualenv
I recently upgraded python from 2.7.6 to 2.7.9 using homebrew. I then tried to 'revirtualise' an existing virtual environment:
sudo virtualenv -p python2.7 existingvenv
But am getting this error:

I also get the above error when running any pip install x inside the above active virtual environment.
I don't get the error when creating a new virtualenv:
$ virtualenv -p python2.7 newvenv
Running virtualenv with interpreter /Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7

Is there an old symlink or something inside the existing virtualenv causing the issue and how can I resolve this?
This is because of a new feature in Python, which wheel 0.24 is not compatible with. You'll find a folder called virtualenv_support containing base install files for setuptools, pip, and wheel under your Python 2.7 system install. There are a few solutions. The easiest is to just remove wheel-0.24* from the virtualenv_support folder. If you want to go a step farther, you could download version 0.26 of the wheel .whl file and replace it.
did you try:
sudo virtualenv --clear -p python2.7 existingvenv
?
I have 2 versions of Python in Centos Linx- Python2.6 & Python2.7..Im trying to create a virtualenv using my virtualenv-2.7 and get the following error.

I've had this problem once.
I think maybe it is the pip problem.
So I follow the below link's instructions and install pip for python 2.7.
wget https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py
sudo /usr/local/bin/python2.7 ez_setup.py
sudo /usr/local/bin/easy_install-2.7 pip
Then
virtualenv -p /usr/local/bin/python2.7 env
worked.
please take a look into the link below.
https://github.com/0xdata/h2o/wiki/Installing-python-2.7-on-centos-6.3.-Follow-this-sequence-exactly-for-centos-machine-only#installing-and-configuring-distribute-setuptools
fyi
I have Mountain Lion and I installed virtualenv using this method:
sudo easy_install pip
sudo pip install virtualenv virtualenvwrapper
echo "export WORKON_HOME=$HOME/Envs" >> $BASH_CONFIG_FILE
echo "source /usr/local/bin/virtualenvwrapper.sh" >> $BASH_CONFIG_FILE
source ~/.bashrc
There is a problem when I try to create the virtualenv with this command:
mkvirtualenv test
I receive this error:

Can you help me?
Thanks!

You don't have setuptools installed,
Install it from here
if you upgraded from lion to mountain lion, the python install is broken due to some changes in the file-system, ideally you should install command line tools from xcode, then python from python website, then setuptools from python website and then pip via easy_install, everything will work afterwards.
Problem solved:
Xcode 4 doesn't automatically install the command line tools.
Basically, install Xcode, go into Preferences and then Downloads and install "Command Line Tools". It works now.
:)
