Python's website has a macOS Python 3 installer we can download and use. If we use the package installation, a python3 fill will be available in /usr/local/bin/. Aliasing is a must since the Python binary stored in /usr/bin/ can't be changed. What's nice about an alias is that it's specific to our command-line shell. Mac os x python free download.

Using Anaconda in a commercial setting? You may need to use Anaconda Commercial Edition. If you have already purchased Commercial Edition, please proceed to the Authenticating Commercial Edition section after completing your installation here.

Haven’t purchased Commercial Edition yet? Visit https://anaconda.cloud/register to get started.

You can install Anaconda using either the graphical installer (“wizard”) or thecommand line (“manual”) instructions below. If you are unsure, choose the graphical install.

macOS graphical install¶

  1. Download the graphical macOS installer for your version of Python.

  2. RECOMMENDED: Verify data integrity with SHA-256.For more information on hashes, see What about cryptographic hash verification?

  3. Double-click the downloaded file and click continue to start the installation.

  4. Answer the prompts on the Introduction, Read Me, and License screens.

  5. Click the Install button to install Anaconda in your ~/opt directory (recommended):

  6. OR, click the Change Install Location button to install in another location (not recommended).

    On the Destination Select screen, select Install for me only.

    Note

    If you get the error message “You cannot install Anaconda in this location,” reselect Install for me only.

  7. Click the continue button.

  8. Optional: To install PyCharm for Anaconda, click on the link to https://www.anaconda.com/pycharm.

    Or to install Anaconda without PyCharm, click the Continue button.

  9. A successful installation displays the following screen:

  10. Verify your installation.

Using the command-line install¶

Use this method if you prefer to use a terminal window.

  1. In your browser, download the command-line version of themacOS installer for your system.

  2. RECOMMENDED: Verify data integrity with SHA-256.For more information on hash verification, see cryptographic hash validation.

    • Open a terminal and run the following:

    Note

    Replace /path/filename with your installation’s path and filename.

  3. Install for Python 3.7 or 2.7:

    • For Python 3.7 enter the following:

    • For Python 2.7, open the Terminal.app or iTerm2 terminal application and then enter the following:

    Note

    Include the bash command regardless of whether or not you are using the Bash shell.

    Note

    Replace ~/Downloads with your actual path and Anaconda3-2020.02-MacOSX-x86_64.sh with actual name of the file you downloaded.

  5. Scroll to the bottom of the license terms and enter yes to agree to them.

  6. The installer prompts you to Press Enter to confirm the location, Press CTRL-C to cancel the installationor specify an alternate installation directory. If you confirm the default location,it will display PREFIX=/home/<user>/anaconda<2or3> and continue the installation.

    Note

    Unlike the graphical install, installing the shell file will place it in ~/anaconda<2 or 3> by default,not ~/opt. This is due to limitations with installing .pkg files on macOS Catalina.

    Installation may take a few minutes to complete.

    Note

    We recommend you accept the default install location. Do not choose the path as /usr for theAnaconda/Miniconda installation.

  7. The installer prompts “Do you wish the installer to initialize Anaconda3by running conda init?” We recommend “yes”.

    Note

    If you enter “no”, then conda will not modify your shell scripts at all.In order to initialize after the installation process is done, first runsource<pathtoconda>/bin/activate and then run condainit.

    Note

    If you are on macOS Catalina, the new default shell is zsh.You will instead need to run source<pathtoconda>/bin/activatefollowed by condainitzsh.

  8. The installer displays “Thank you for installing Anaconda!”

  9. Optional: The installer describes the partnership between Anaconda and JetBrains andprovides a link to install PyCharm for Anaconda athttps://www.anaconda.com/pycharm.

  10. Close and open your terminal window for the Anaconda installation to take effect.

  11. To control whether or not each shell session has the base environmentactivated or not, run condaconfig--setauto_activate_baseFalseorTrue. To run conda from anywhere without having the base environmentactivated by default, use condaconfig--setauto_activate_baseFalse.This only works if you have run condainit first.

    Note

    condainit is available in conda versions 4.6.12 and later.

  12. Verify your installation.
