if you want to install a specific version then, you must check before install. To uninstall Python 3 on Mac completely and safely, please follow the steps below. This is another package manager but based and mainly meant for python, it also gives the equivalent of python's virtual environments and pyenv (as per other answer) and so each project can be in a different python and different libraries (Macports only switches python version for all projects) The issue with Homebrew is that it assumes that things in /usr/local are installed by it and so brew doctor will report these pythons and libraries as issues and as this question shows also the frameworks in /Library will be problematic.ĮDIT 8/2018 *** I would now suggest using conda either miniconda or anaconda. The other way is install direct from This will install a python into /usr/local/bin I think this installs a python and python3 executable. e,g, to select macports python 2.7 port select -set python python27Įach package manager needs to run as the only package manager otherwise it will be confused with unexpected different versions of libraries and executables on its paths.įrom comments the similar homebrew way is given in Short answer seems to be brew switch the equivalent to port_select Python version managers For example to install 3.4 do sudo port install python34 There is also a python_select port that running it allows you to choose which version of python is run by /opt/bin/python. There are separate ports for several python versions 2.x and 3.x currently 2.4, 2.5, 2.6, 2.7 and 3.1, 3.2, 3.3 3.4 and 3.5. The first is using Macports as the package manager. Once your PIP workflow is ready, you can start installing packages from PyPI.I have done this sort of thing in two ways - however both do not coexist with homebrew although I suspect there should be a way similar to the macports one.

The easiest way to do that is to install one of the binary installers for OS X from the Python Download page. However, to take advantage of the latest versions of Python, you will need to download and install newer versions alongside the system ones.

Read our guide on how to set up and use a virtual environment. Python comes pre-installed on Mac OS X so it is easy to start using. Since Python can’t differentiate between versions in the “site-packages” you need to create isolated environments for Python projects. Maybe Project A requires version 1, but Project B needs version 2. You’ll start facing problems when you require a different version of library C. Let’s say you’re working on two projects: A and B, both of which have a dependency on the same library C. At first glance, it may seem fine but imagine this situation. That’s because every project on your system will use “site-packages” to store and retrieve packages. Once you have a base installation of a Python setup, don’t start installing packages directly into it with PIP. Yum Package Manager sudo yum install python3 python3-wheel Install and Configure Virtual Environment
How to install python on mac update#
Open Terminal, then type in: brew install openssl readline sqlite3 xz zlibĪt last, we’ll need to update the shell profile configuration, i.e, ~/. To make pyenv work, we’ll first install build dependencies through Homebrew.

The Homebrew Python documentation knows about this problem and recommends pyenv to manage Python environments. You lose control over “site-packages” and all the PIP packages that you had installed might become inaccessible. It can happen when other Homebrew-based packages (e.g., youtube-dl) use Python as its dependency gets updated.

We’ll use Homebrew for installing software packages but not for Python development. If you’re working on multiple Python projects, some at work or for other side-projects, the location itself (needs sudo privileges) creates hurdles.
