I would do the following 👇🏾: ## Step 1: Install Dependencies Before installing Pyenv, install all the build dependencies shit: ```bash sudo apt update sudo apt install -y build-essential libssl-dev zlib1g-dev libbz2-dev \ libreadline-dev libsqlite3-dev wget curl llvm libffi-dev liblzma-dev \ python3-openssl git ``` ## Step 2: Install Pyenv You can install Pyenv using the automatic installer. Run the following command in your terminal: ```bash curl https://pyenv.run | bash ``` This command downloads and runs the Pyenv installer script, which sets up Pyenv and its associated tools. ## Step 3: Configure Your Shell After installation, you need to add Pyenv to your shell's configuration file to ensure it loads every time you open a terminal. Depending on the shell you are using (e.g., Bash or Zsh), you will need to add the following lines to your `~/.bashrc` or `~/.zshrc` file: ```bash export PYENV_ROOT="$HOME/.pyenv" export PATH="$PYENV_ROOT/bin:$PATH" eval "$(pyenv init --path)" eval "$(pyenv init -)" ``` To do this, you can use a text editor like `vim` or `nvim` in my case: ```bash vim ~/.bashrc ``` Add the lines above at the end of the file, save, and exit. ## Step 4: Apply Changes To apply the changes made to your shell configuration, run: ```bash source ~/.bashrc ``` This command reloads the configuration file, making Pyenv available in your current terminal session. ## Step 5: Verify Installation To confirm that Pyenv is installed correctly, run: ```bash pyenv --version ``` If installed successfully, this command will display the version of Pyenv. ## Step 6: Install Python Versions Now that Pyenv is set up, your friend can install different Python versions. For example, to install Python 3.10.0, they can run: ```bash pyenv install 3.10.0 ``` To set a global Python version, use: ```bash pyenv global 3.10.0 ```
