To make pyenv work, install build dependencies through Homebrew. The Homebrew Python documentation recommends pyenv to manage Python environments. You lose control over “site-packages” and all the PIP packages that you had installed might become inaccessible. For example, the "youtube-dl" package uses Python as its dependency, the Python package may get updated as and when needed. Many people prefer to use Homebrew to install software packages, but should you use it for Python development? The problem with using Homebrew Python is that it’s not in your control. The commands to install brew are provided below.If you’re working on multiple Python projects, the default location, which needs sudo privileges, creates hurdles. It's a widely used dependency manager for Mac OS that provides installation packages for many open-source software projects.
Many developers may already have homebrew installed. We will walk through the most common installation scenarios here, but if you encounter issues, consult the full installation instructions for the project: ĭifferent operating systems have different dependency needs, the latest of which are documented here: Installing pyenv on Mac OS using homebrew #
virtualenv is still widely used - but it lacks some crucial features that pyenv provides for standardized installation methods. Prior to pyenv becoming popular, many python developers used virtualenv to manage environment versions. It's similar to the better-known tool that is commonly used in ruby development - rbenv. It allows developers to define which version of python to use on a per-project basis. Pyenv is an open-source tool used for managing multiple python environments. Fortunately, there is a tool called pyenv that will allow us to safely install the latest python version - regardless of whether we have a system python version installed or not. Updating it can break certain tools that our operating system needs for essential tasks, including dependency management software. In cases where older are versions present, it is unsafe to update system python directly. In other cases, the command above could fail completely, indicting that python is not installed at all. The output above indicates that the system version of python installed is much older than 3.7.
