Answer 1

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.
