By default, if you close your Terminal, the environment is deactivated.

Once an environment is activated, all the install commands will apply only to the current environment. You can read more about Python environments in the documentation.

Next, let’s follow best practices and create a new Python environment, named work (feel free to use a different name), in which we can install NumPy, SciPy and Matplotlib: 1 python3.9 -m venv work 2 source work/bin/activateĪt this point, your prompt should indicate that you are using the work environment. This is what I see if I run python3.9 on my machine: 1 % python3.9Ģ Python 3.9.3 (v3.9.3:e723086bc3, Apr 2 2021, 08:20:09) 3 on darwin 4 Type "help", "copyright", "credits" or "license" for more information.
python3 will also invoke the latest installer version of Python 3. If this is the case, you can select which version you want to use by specifying the version number, e.g.: 1 python3.8Īfter the above, you can invoke Python 3.9 using the python3.9 command. You can have multiple Python 3 versions installed on your macOS machine. The official installer of Python is a pkg file that will start a GUI installer which will guide you through the installation. In this article, we are going to use the latest stable version of Python which, at the time of this writing is 3.9. Once the Command Line Tools are installed, we can install Python.Īs a side note, after you install the Command Line Tools, you will also get a slightly older Python 3 version (3.8). Open a Terminal and write: 1 xcode-select -install Please note, that you will need the Command Line Tools even if you’ve already installed Xcode. Start by installing the Command Line Tools for macOS.
In this tutorial, we’ll use Python 3.9 which is the latest stable release of Python at the time of this writing. Python 3 is the future and it is supported by all major Python libraries. MacOS Big Sur comes by default with Python 2.7 which, at this point, receives only bug fixes and is EOL since 2020. If you have an arm64 Mac, also called Apple Silicon, please check my other article.

In this article, I will show you how to install Python with NumPy, SciPy and Matplotlib on macOS Big Sur. Change the URL if necessary.Solarian Programmer My programming ramblings Home Archives Contact Privacy Install Python with NumPy, SciPy and Matplotlib on macOS Big Sur (Intel version) Posted on Octoby Paul Please note that python3.rb was renamed to python.rb at some point. There is also: where you can install using brew install sashkab/python/python34 and brew link python34 -force
Now you can use brew install with the corresponding commit hash: if you want to install a specific version then, you must check before install. 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. 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.
