Installing Python Runtime Versions via Pyenv

In order to test different Python Runtime versions, I have installed some versions.

$ pyenv install 3.10.2

python-build: use openssl@1.1 from homebrew
python-build: use readline from homebrew

How to install Python with pyenv runtime version manager

Posted on by admin

I am using different programming languages like C#, Java, Node.js etc and need to manage runtime versions in my local. So, I like to use runtime version managers.

For example, there are some runtime version managers in Node.js community like nvm or n. I am very happy to use both of two package managers 🙂

Let's say I work for one Node.js project in dev machine with Node v8.0.0 but other project needs Node v6.0.0

In order to handle, different versions in same machine, we may use runtime version managers.

I just want to find a way to switch between different Python version so that found pyenv runtime version manager.

Pyenv installation

Click pyenv link for more detailed installation.

Installing pyenv with Homebrew

First, ensure that you have Homebrew installed in your system. Homebrew is a package manager for Mac OS. So if you want to learn more details about it, visit my blog below.

Homebrew package manager for Mac OS and Linux

Run the following commands in your terminal. But, just copy commands without $ sign.

$ brew update
$ brew install pyenv

Setting PATH

Run the following command for advanced configuration.

$ echo -e 'if command -v pyenv 1>/dev/null 2>&1; then\n  eval "$(pyenv init -)"\nfi' >> ~/.bash_profile

Run the following command for basic configuration.

$ echo 'PATH=$(pyenv root)/shims:$PATH' >> ~/.bash_profile

and restart your terminal manually or run the following command to restart automatically.

$ exec "$SHELL"

Upgrading pyenv

$ brew upgrade pyenv

Uninstall pyenv

$ rm -rf $(pyenv root)
$ brew uninstall pyenv
