![]() ![]() This will start the virtual environment and you should see the name of the virtual environment added before the directory name as shown in the image below: To activate the virtual environment, run the following command: source my_env/bin/activate This will create a virtual environment for you with the following files in the virtual environment directory my_env: We can run the following command to create a virtual environment: python3 -m venv my_env Each virtual environment has its own Python binary (which matches the version of the binary that was used to create this environment) and can have its own independent set of installed Python packages in its site directories. The venv module provides support for creating lightweight “virtual environments” with their own site directories, optionally isolated from system site directories. Use venv to create a Virtual EnvironmentĪs per the official documentation of venv module, To verify the successful installation of the Python 3.x version, run the python3 command, and the IDLE should start in your terminal. Homebrew will also install pip for you which you can verify by running the pip3 command. Once you have Homebrew set up, run the following command to install the latest version of Python: $ brew install python If you don't have Homebrew installed on your Macbook, you can install Homebrew on your MacOSX and then use it to install Python 3.8 on your machine. We will use Homebrew to install Python 3.8 and will then move on to creating a virtual environment. So to set up a virtual environment, we won't be using virtualenv or virtualenvwrapper module, which are the most popular to set up a virtual environment.īut we will be using the venv module which comes as a default with Python 3.x version and is recommended to use for virtual environment creation. You can set up a different virtual environment for each project for example if you are working on one project based on Tkinter module, or some other projects based on the Numpy module, then you can easily do this. We can have different versions of Python installed inside the virtual environment. When we have a virtual environment, then we can install new packages inside the virtual environment which will not affect the operating system's python modules. You must be thinking about why we need a virtual environment. Instead, you should set up a virtual environment for your development purpose. If you are a Mac user, you should know that Python 2.7.x comes pre-installed in your Macbook, but as that is required by your operating system, you cannot modify it or update it and I would recommend that you don't use it at all. They allow you to create a self-contained space for each project, where you can install specific versions of Python packages without worrying about conflicts with your system-wide installations.īy the end of this article, you will have a solid understanding of how to set up a Python virtual environment on your Mac and get started on your coding endeavors hassle-free. Whether you're a seasoned developer or just starting your coding journey, understanding virtual environments is crucial. Setting up a virtual environment on macOS can seem like a daunting task, but fear not! In this article, we will guide you through the easiest way to set up a Python virtual environment on your Mac. With this setup, you'll be able to keep your system macosx python and switch to whatever new version of python you want available through pyenv.Python virtual environments are essential tools for managing project dependencies and ensuring a clean, isolated development environment. ![]() Note: you may need to create a new shell or reload your bash_profile in your current shell for the pyenv initialization to do its thing (set up shims). Now install some python using pyenv and then switch to it with the pyenv local command (you can see all your versions with pyenv versions). If command -v pyenv 1>/dev/null 2>&1 then Once you have pyenv installed, update your.Install homebrew if you don't already have it and use it to install pyenv with brew install pyenv.The pyenv repo is pretty detailed on how to install for different systems and what it's actually doing, but here's the basic steps for mac: Modify your shell environment ( PATH) with shims so that when you do pyenv local 3.8.1, calling python will invoke the new interpreter instead of your system python.Doing pyenv install 3.8.1 will install python 3.8.1 under ~/.pyenv/versions/3.8.1. Install different python versions under some directory. ![]() Essentially, pyenv can do two key things for you: I recommend using pyenv to manage your local python versions (both 2.x and 3.x) instead of installing new versions directly with homebrew or building new python versions from source manually. ![]()
