virtualenv venv --python=python3.7 returns command not found in console

Question

I am trying to create a virtual environment by executing this command: virtualenv venv --python=python3.7 but it returns 'command not found' error

have you not installed [`virtualenv`](https://docs.python-guide.org/dev/virtualenvs/#lower-level-virtualenv) yet? — chickity china chinese chicken, Nov 16 '18 at 01:51

Personally, I think virtualenv is deprecated now that venv comes with Python 3.7 (https://docs.python.org/3/library/venv.html).

Virtual environments are created like so with venv (according to the docs):

    python3 -m venv /path/to/new/virtual/environment

I don't think venv is a virtualenv command (https://virtualenv.pypa.io/en/stable/userguide/#usage; https://packaging.python.org/tutorials/installing-packages/#creating-virtual-environments), and at least not for what you are trying to do. The command for new virtual environments with virtualenv is virtualenv ENV.

If you're a Mac user then `venv` will also set up Python as a framework. This makes Matplotlib's default renderer work. I've switched to `venv` just for this feature. — Adam, Nov 16 '18 at 02:28

maybe you should install virtualenv first:

pip install virtualenv

maybe you should check the virtualenvwrapper, which is based on virtualenv and much easier to manage your virtual environment.
