If it doesn’t find this file, then it looks for the user-level file ~/.pyenv/version.Īnd this is essentially all there is to it. python-version in the current directory to decide which version of python to run. When you try to run Python, it first looks for a. Pyenv’s magic works because it actually redefines your Python command: ~$ which python This ensures that pyenv remains working as normal after you leave the virtualenv. This last command is the recommended way to deactivate the virtualenv. Here I used Python 3.4 to create the virtualenv (Note that if you want to create a virtualenv from the system Python, then virtualenv needs to be installed at the system level as well). Requirement already satisfied (use -upgrade to upgrade): pip in /home/staff/jmoreira/.pyenv/versions/venv/lib/python3.4/site-packages Requirement already satisfied (use -upgrade to upgrade): setuptools in /home/staff/jmoreira/.pyenv/versions/venv/lib/python3.4/site-packages ~/virtual_env$ pyenv virtualenv 3.4.0 venv This plugin adds complete virtualenv functionality to pyenv: git clone ~/.pyenv/plugins/pyenv-virtualenv If you can’t function without your virtual environments anymore then fear not, for there is a plugin for that: pyenv-virtualenv. In contrast, virtualenv makes use of symbolic links to decrease the size of the virtualenv’s. The main difference is that pyenv actually copies an entire Python installation every time you create a new pyenv version. Indeed, a local Python created from pyenv is almost like a Python virtual environment. To other virtualenv users, the idea of a local Python might seem familiar. You can also use pyenv to define a project-specific, or local, version of Python: ~$ pyenv global system To use python 3.4 as the global one we do: pyenv global 3.4.0 pyenv install –list will show all available Python versions to install). (By the way, there is no need to memorize these. Installed Python-3.4.0 to /home/staff/jmoreira/.pyenv/versions/3.4.0 Installed readline-6.3 to /home/staff/jmoreira/.pyenv/versions/3.4.0 For instance, let’s go now to the cutting edge of python: ~$ pyenv install 3.4.0 Let’s start by installing another python version. pyenv now allows you to expand upon this version. That’s what’s shown in the above command.
Usually you will only have one version of python installed, the system-wide version. * system (set by /home/staff/jmoreira/.pyenv/version) This is the one-liner provided by the automatic installer. pyenvĮcho 'export PYENV_ROOT="$HOME/.pyenv"' > ~/.bashrcĮcho 'export PATH="$PYENV_ROOT/bin:$PATH"' > ~/.bashrcĮcho 'eval "$(pyenv init -)"' > ~/.bashrc This works best for our Ubuntu 12.04 workstations which default to a.

If you're using a Mac, I highly recommend installing pyenv with Homebrew (none of that MacPorts shenanigans). So let’s start! Installationįollow the installation instructions or use the automatic installer. All this is done on *NIX-style machines (Linux and OS X) without depending on Python itself and it works at the user-level–no need for any sudo commands. Previously known as Pythonbrew, pyenv lets you change the global Python version, install multiple Python versions, set directory (project)-specific Python versions, and yes create/manage virtual python environments ("virualenv's").
