I have installed python2 and python3 with Homebrew. I would like to use virtualenv

  • 0

I have installed python2 and python3 with Homebrew. I would like to use virtualenv but I am not sure if I need to install it for both python2/python3. I am also wondering if I use virtualenvwrapper can I just set the VIRTUALENVWRAPPER_PYTHON to be either python2 or python3 depending on my needs?

Any help is greatly appreciated.

Thanks,
Greg

    According to this SO question, you could use a single virtualenv for both version, just use the -p path/to/python/version or --python=path/to/version flag to specify which version to use for the creation of the virtual environment. Note that you can use the same flag with mkvirtualenv.

    This post recommends to just use the system Python (2.7 in your case) to install virtualenv itself.
