echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.bashrc echo 'export PATH="$PYENV_ROOT/bin:$PATH"' >> ~/.bashrc echo -e 'if command -v pyenv 1>/dev/null 2>&1; then\n eval "$(pyenv init -)"\nfi' >> ~/.bashrc
Finally, restart the shell by running: to begin utilizing pyenv.
root@ubuntu:~# exec "$SHELL"
Step 4: Look over the Installation
We will attempt to install a fresh copy of Python to make sure Pyenv is set up properly. The Python versions that are currently available are listed first:
root@ubuntu:~# pyenv install --list
The list of versions that are offered is extensive. Let’s install Python version 3.8.3 now:
root@ubuntu:~# pyenv install 3.8.3 Downloading Python-3.8.3.tar.xz... -> https://www.python.org/ftp/python/3.8.3/Python-3.8.3.tar.xz Installing Python-3.8.3... Installed Python-3.8.3 to /root/.pyenv/versions/3.8.3
If this command takes a while to execute, do not be alarmed. Pyenv is building this version of Python from the source code.
Run the pyenv versions command to see if Python 3.8.3 has now been installed:
root@ubuntu:~# pyenv versions * system (set by /root/.pyenv/version) 3.8.3
Change Python to version 3.8.3 and then drop it into a Python shell to perform additional checking.
root@ubuntu:~# pyenv global 3.8.3 root@ubuntu:~# python Python 3.8.3 (default, Jun 10 2020, 22:45:23) [GCC 7.5.0] on linux Type "help", "copyright", "credits" or "license" for more information. >>>
