![]() How toĪpproach the scenario with multiple projects with different package versions? PoetryĪlright, now that we can control multiple Python versions on our system. python-version which basically tells pyenv which version to Level, we can use pyenv local, for example pyenv local 3.9.15. If we have multiple versions and want to set a specific version on a folder Maintains lightweight executables that pass python commands along to pyenv. This shims directory is inserted at theįront of your $PATH (check with echo $PATH) and it’s a directory to matchĮvery Python command across every installed version of Python. If you run which python, you’ll see an interesting path Global Python version use pyenv global 3.10.4, and check python -V to ![]() If you are using Ubuntu:Īs you can see, we are using the system’s Python version. That we’ll need some library dependencies installed before we use it.ĭependencies will vary depending on your OS. It’s important to mention that pyenv builds python from source, which means Which Display the full path to an executable ![]() Whence List all Python versions that contain the given executable Virtualenvs List all Python virtualenvs found in `$PYENV_ROOT/versions/*'. Virtualenv-prefix Display real_prefix for a Python virtualenv version Virtualenv-init Configure the shell environment for pyenv-virtualenv Virtualenv-delete Uninstall a specific Python virtualenv Virtualenv Create a Python virtualenv using the pyenv-virtualenv plugin Versions List all Python versions available to pyenv Version-origin Explain how the current Python version is set Version-name Show the current Python version Version-file Detect the file that sets the current pyenv version Version Show the current Python version(s) and its origin Shell Set or show the shell-specific Python version Root Display the root directory where versions and shims are kept Rehash Rehash pyenv shims (run this after installing executables) Prefix Display prefixes for Python versions Local Set or show the local application-specific Python version(s) Latest Print the latest installed or known version with the given prefix Install Install a Python version using python-build Init Configure the shell environment for pyenv Hooks List hook scripts for a given pyenv command Global Set or show the global Python version(s) InstallationĬommands List all available pyenv commandsĭeactivate Deactivate virtual environmentĭoctor Verify pyenv installation and development tools to build pythons.Įxec Run an executable with the selected Python version It lets you easily switchīetween multiple versions of Python. Is a simple Python version management tool. Ubuntu on work laptop, and a colleague is using the same setup on Which will allow you to experiment without breaking your OS environment. I suggest you use Windows Subsystem for Linux (WSL) or run a Docker image, This guide is primarily for unix-like systems. I hope this will help you, and please don’t hesitate to reach out with Guide and reference for those that are just starting with Python or switchedįrom other programming languages and are not quite sure how things work in the ![]() Python projects with different versions of packages or Python itself.Ĭonsequently, I’ve decided to write a small post that will serve as a quick Things even got messier when there were multiple Install the following dependencies if they aren’t already.Some of my colleagues and friends had troubles setting up their local machinesįor working on Python projects. First of all, make sure the virtualenvwrapper is already installed in your machine then follow the steps below. I personally use virtualenvwrapper so that’s what I’m going to show you here. From version 3.3 onwards, Python has included the venv module for creating virtual environments as part of its standard library. For python 2.7-3.4, virtualenvwrapper is probably your best option. Virtual environments allow you to sandbox multiple Python versions depending on your development needs so that you don’t have to upgrade or downgrade your system’s Python version. Now, if you feel that these versions are outdated and you want to try the newer Python versions, the best course of action is to use virtual environments. In the case of Xubuntu 14.04 (Trusty Tahr), the Python versions that come with it are 2.7.6 and 3.4.3. If you’re running Ubuntu, you should avoid upgrading or modifying the Python version that came with your system because doing so could lead to unwanted results, conflicts, and even system breakage.
