virtualenv can't find python2

Question

I'm on a mac, which comes with python 2.7 installed, so I should have the required version.

At least, I believe that's the problem. I'm getting an error when trying to run make install for a project, and getting the following error:

The executable python2 (from --python=python2) does not exist
make: *** [bin/python] Error 3

Answer 1

virtualenv --python=python3 fibonacci_env

Point out which python

Answer 2

Specify the full path to the Python interpreter (not sure if this is the right path - haven't used MacOs):

mkvirtualenv myenv --python=/Library/Frameworks/Python.framework/Versions/2.7/bin/python

or smth like:

--python=$(which python)

Answer 3

Python 2.7 is part of system framework and is located here:

/System/Library/Frameworks/Python.framework/Versions/

If you want to create a virtualenv with python2.7 on macOS Sierra do this:

virtualenv -p /System/Library/Frameworks/Python.framework/Versions/2.7/bin/python my_venv

Answer 4

Specify the python version you want to use

virtualenv -p /usr/bin/python3 venv
