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
New python executable in venv/bin/python
Installing setuptools, pip, wheel...
Complete output from command /Users/alex/kartograph-test/venv/bin/python -c "import sys, pip; sys...d\"] + sys.argv[1:]))" setuptools pip wheel:

now when I try and create it with /usr/local/bin/python2.7 I get

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?
virtualenv venvvenvfolder before re-creating an env?
