Sure, installing multiple Python versions on Ubuntu can be useful for different projects that may have specific version requirements. Here's a step-by-step tutorial on how to install and manage multiple Python versions using pyenv:
Before installing any software, it's a good practice to ensure that your system is up to date:
To avoid potential issues during the installation of Python versions, install the required dependencies:
pyenv is a Python version manager that makes it easy to install and manage multiple Python versions. Clone the pyenv repository and add the necessary configuration to your shell profile (e.g., ~/.bashrc or ~/.zshrc):
After adding these lines, restart your terminal or run source ~/.bashrc (or source ~/.zshrc for Zsh users).
With pyenv installed, you can now install multiple Python versions. For example, let's install Python 3.8 and Python 3.9:
After installing multiple Python versions, you can set a global version or set a local version for a specific project.
Set the global Python version:
Set the local Python version for a specific directory (create a .python-version file in your project directory):
You can verify that the correct Python version is being used by running:
This should display the version you set globally or locally.
Now you have successfully installed and managed multiple Python versions on your Ubuntu system using pyenv. This allows you to work on different projects with their specific Python version requirements.
