But this method of getting Python on macOS is fastest and cleanest to get you going on your own data scientist laptop without a VM nor a container. You can see most of its installation on /Library/Developer/CommandLineTools folder.įor production and high end processing I’ll still use Python on Linux with my preferred distribution’s default packages (no Anaconda). Xcode Command Line Tools will get you a full hand of other useful developer tools, such as git, subversion, GCC and LLVM compilers and linkers, make, m4 and a complete Python 3 distribution. Now I can simply type jupyter-lab anywhere in the terminal or command line to make it fire my browser and get a Jupyter environment. So lets just use the binary that works better: export PATH=/Library/Developer/CommandLineTools/usr/bin:$PATHĬommands installed by pip3 will be available in the ~/Library/Python/3.7/bin/ folder, so just add it to your PATH: export PATH=$PATH:~/Library/Python/3.7/bin/ The one that gets installed on /usr/bin/python3 has problems loading some libraries and instrumentation with install_name_tool would be required. After downloading that, navigate to your Downloads directory (if you’re new to the Terminal, just open the Terminal application and type cd HOME/Downloads ). The following command will install the latest version of a module and its dependencies from the Python Package Index: python -m pip install SomePackage Note For POSIX users (including macOS and Linux users), the examples in this guide assume the use of a virtual environment. LDFLAGS="-L/Library/Developer/CommandLineTools/Library/Frameworks/amework/Versions/3.7/lib" \įor some reason, Apple installs many different Python 3 binaries in different places of the system. I went to the Anaconda downloads page and got the Python 2.7 Mac OS X 64-Bit command-line installer, so that we can install everything from Terminal. Set yourself at home and install them with pip3.įor modules that require compilation and special library, say crypto, do it like this: CFLAGS="-I/Library/Developer/CommandLineTools/Library/Frameworks/amework/Versions/3.7/include" \ For my personal use, I need the complete machine learning, data wrangling and Jupyter suite: pip3 install -user sqlalchemyīut you might need other things as Django or other sqlalchemy drivers. Don’t forget to use –user to get things installed on your home folder so you won’t pollute your overall system. Now that you get a useful Python 3 installation, use pip3 to install Python modules that you’ll need. Rm -rf $/Library/Caches/pip Install Python Modules In case you already have Python installed under your user and modules downloaded with pip, remove it: If you already have complete Xcode installed, this step was unnecessary (you already had Python 3 installed) and you can continue to the next section of the tutorial. Settings window will pop so wait 5 minutes for the installation to finish. This way, every time Apple releases an update, you’ll get it. To get it installed (without the heavy Xcode GUI), type this in your terminal: xcode-select -install Python 3 is shipped by Xcode Command Line Tools. You don’t need to get the awful Anaconda on you Mac to play with Python. ![]() But you can still get 3 from Apple, updated regularly through system’s official update methods. MacOS Catalina doesn’t ship with Python 3, only 2.
