How to Install pyenv Command on Generic Linux

If you’re using a Generic Linux distribution and you encounter the “pyenv: command not found” error, don’t worry. This tutorial will guide you through the installation process of pyenv, a popular Python version management tool.

Introduction to pyenv

pyenv is a tool that allows you to easily switch between multiple versions of Python on your system. It helps you manage different Python versions and dependencies for different projects, making it a valuable tool for developers working on Python projects.

Installation Steps

Follow these steps to install pyenv on your Generic Linux system:

1. Install Dependencies:

   sudo apt-get update
   sudo apt-get install -y make build-essential libssl-dev zlib1g-dev libbz2-dev libreadline-dev libsqlite3-dev wget curl llvm libncurses5-dev libncursesw5-dev xz-utils tk-dev libffi-dev liblzma-dev python-openssl
   

2. Clone pyenv:

   git clone https://github.com/pyenv/pyenv.git ~/.pyenv
   

3. Set up environment variables:

   Add the following lines to your shell configuration file (e.g., ~/.bashrc, ~/.zshrc):

   export PYENV_ROOT="$HOME/.pyenv"
   export PATH="$PYENV_ROOT/bin:$PATH"
