Answer 1

If you're using pyenv, I would recommend building a pyenv controlled virualenv (make sure pyenv-virtualenv is installed first)

$ pyenv virtualenv 2.7 <your new env>

Which you can then switch to this virtualenv using pyenv

$ pyenv local <your new env>

or

$ pyenv shell <your new env>

Answer 2

for python2.7

virtualenv -p /usr/bin/python2.7 my_env
