I had used pyenv to manage several Python versions. However, on macOS Big Sur, it didn’t work well. Here, I introduce a way to install Python 3.9.1 using installer which can be downloaded from official site.

Install Python using installer

Visit official site and download installer. In my case, I chose macOS 64-bit Intel Installer.

Install the Python using downloaded installer. That’s it. Now you can use python3.9 and pip3.9 on terminal.

Upgrade pip3.9

Upgrade pip3.9 by the following command:

pip3.9 install --upgrade pip

(optional) Install pipenv

Install pipenv by the following command:

pip3.9 install --user pipenv

(optional) Install poetry

Alternatively, you can use poetry. Install poetry by the following command:

pip3.9 install --user poetry

That’s it. Now you can move to start Python project in my previous post.
