I just encountered the same problem.
It turns out I was using python-2.7.13 and downgrading to 2.7.10 solved that issue.
If you are using Anaconda, you can do that by running:
$ conda install python=2.7.10

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!

Any ideas on how to fix this? I already try this, worked fine, but using mkvirtualenv still no good.
This seems to be an issue specific to using Anaconda. You can create a virtualenv with the default python:
mkvirtualenv test -p /usr/bin/python
I'm trying to follow the directions on the Flask installation website but I encountered an error after I used "sudo easy_install virtualenv" to install virtual environment. Not sure

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 don't know the reason, but the function mkvirtualenv is ending in the following error:

It is was working before and now I am getting this error. Does someone can help me?
Thanks in advance,

Looks like you are using Anaconda Python. You should be using Conda to do this not virtenv.
Try:
LEP:~ lep$ conda create --name myenvironment
Try downgrading to python version 2.7.9
conda install python=2.7.9
Kudos to folks here in the GitHub conda issues section
Addendum: Thanks, Josh Trii Johnston for his comment which basically said the same thing I did... I didn't see that before.
I've been following this tutorial:
https://python-guide.readthedocs.org/en/latest/dev/virtualenvs/
when i type this into terminal:
virtualenv venv
A folder pops up in my directory, as expected, but there is no 'activate' file. only python, python2, and python2.7
I tried this only to get command not found.
AJs-MacBook-Pro-4:petrarch AJ$ source venv/bin/python2.7
-bash: ????: command not found
Sorry! please help this newb.
When I type in virtualenv venv again, i get this:
