--- title: Install Python and Jupyter on macOS with Minimal Effort date: 2017-02-28 11:14:00 +09:00 redirect_from: "/blog/2017/02/28/minimal-python-jupyter-macos" --- Maybe you don't need `pyenv` and/or `virtualenv` in most cases. ## Install Python > Don't have `brew`? Go to . ``` brew install python ``` If you still need Python 2, run `brew install python@2`. ## Install Jupyter Notebook ``` pip install jupyter python -m ipykernel install --user ``` That's all. # How about `virtualenv`? Since Python 3 got its own virtual environment tool called [venv](https://docs.python.org/3/library/venv.html), You no longer need `virtualenv`. If you want a virtual envs on your project, run: ``` python -m venv venv source ./venv/bin/activate ``` then `venv` will creates virtual envs on **./venv** folder on the root of your project.
