Install a Custom Python Version

This guide explains how to install your own Python version without root access using pyenv.

1. Clone pyenv:

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

2. Configure your shell:

cat >> ~/.bashrc << 'EOF'
export PYENV_ROOT="$HOME/.pyenv"
export PATH="$PYENV_ROOT/bin:$PATH"
eval "$(pyenv init - bash)"
EOF

source ~/.bashrc

3. Install your preferred Python version (replace 3.13.5 with any version you need):

pyenv install 3.13.5

4. Set it as your default Python version:

pyenv global 3.13.5

5. Verify the installation:

python --version
python3 --version
pip --version

Your custom Python installation is now ready to use.

Install Another Python Version

You can install additional Python versions at any time.

Example:

pyenv install 3.12.11
pyenv global 3.12.11

Verify the active version:

python --version

List Installed Versions

pyenv versions

Switch Between Installed Versions

To change the default Python version:

pyenv global 3.13.5

For the current shell only:

pyenv shell 3.13.5

Uninstall a Python Version

To remove a specific Python version:

pyenv uninstall 3.13.5

Remove pyenv Completely

If you no longer need pyenv, remove it with:

rm -rf ~/.pyenv

Then remove the pyenv lines from your ~/.bashrc and reload your shell:

source ~/.bashrc

Notes

• No root access is required.
• You can install multiple Python versions simultaneously.
• Replace 3.13.5 with any Python version supported by pyenv.
