- Little did I know that this would make my Anaconda installation a tiny bit more difficult. One single line of code more difficult, as it turns out, but a million times more challenging for a newbie. This is the step-by-step installation process with a simple one-line fix that will allow you to “conda” anything you want.
This tutorial provided a quick guide to install Anaconda on Mac as well as dealing with a common installation issue. A graphical install of Anaconda isn’t the only way to install Anaconda as you can Install Anaconda by a Command Line Installer, but it is the easiest.
Note
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¶
Download the graphical macOS installer for your version of Python.
RECOMMENDED: Verify data integrity with SHA-256.For more information on hashes, see What about cryptographic hash verification?
Double-click the downloaded file and click continue to start the installation.
Answer the prompts on the Introduction, Read Me, and License screens.
Click the Install button to install Anaconda in your ~/opt directory (recommended):
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.
Click the continue button.
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.
A successful installation displays the following screen:
Verify your installation.
Using the command-line install¶
Use this method if you prefer to use a terminal window.
In your browser, download the command-line version of themacOS installer for your system.
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.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 andAnaconda3-2020.02-MacOSX-x86_64.sh
with actual name of the file you downloaded.The installer prompts “In order to continue the installation process, please review the license agreement.”Click Enter to view the license terms.
Scroll to the bottom of the license terms and enter yes to agree to them.
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.
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 run
source<pathtoconda>/bin/activate
and then runcondainit
.Note
If you are on macOS Catalina, the new default shell is zsh.You will instead need to run
source<pathtoconda>/bin/activate
followed bycondainitzsh
.The installer displays “Thank you for installing Anaconda!”
Optional: The installer describes the partnership between Anaconda and JetBrains andprovides a link to install PyCharm for Anaconda athttps://www.anaconda.com/pycharm.
Close and open your terminal window for the Anaconda installation to take effect.
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, usecondaconfig--setauto_activate_baseFalse
.This only works if you have runcondainit
first.Note
condainit
is available in conda versions 4.6.12 and later.Verify your installation.
What’s next?¶
Get started programming quickly with Anaconda in the Getting started with Anaconda guide.
Download the installer:
Miniconda installer for macOS.
Anaconda installer for macOS.
Verify your installer hashes.
Install:
Miniconda---In your terminal window, run:
Anaconda---Double-click the
.pkg
file.
Follow the prompts on the installer screens.
If you are unsure about any setting, accept the defaults. Youcan change them later.
To make the changes take effect, close and then re-open yourterminal window.
Test your installation. In your terminal window orAnaconda Prompt, run the command
condalist
. A list of installed packages appearsif it has been installed correctly.
Installing in silent mode¶
Note
The following instructions are for Miniconda. For Anaconda,substitute Anaconda
for Miniconda
in all of the commands.
To run the silent installation ofMiniconda for macOS or Linux, specify the -b and -p arguments ofthe bash installer. The following arguments are supported:
-b---Batch mode with no PATH modifications to
~/.bashrc
.Assumes that you agree to the license agreement. Does not editthe.bashrc
or.bash_profile
files.-p---Installation prefix/path.
-f---Force installation even if prefix -p already exists.
EXAMPLE:
The installer prompts “Do you wish the installer to initialize Miniconda3 by running condainit
?” 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 run source<pathtoconda>/bin/activate
and then run condainit
.
MacOS Catalina
If you are on macOS Catalina, the new default shell is zsh. You will instead need to run source<pathtoconda>/bin/activate
followed by condainitzsh
.
Updating Anaconda or Miniconda¶
Open a terminal window.
Navigate to the
anaconda
directory.Run
condaupdateconda
.
Uninstalling Anaconda or Miniconda¶
Anaconda Command Prompt
Open a terminal window.
Remove the entire Miniconda install directory with:
OPTIONAL: Edit
~/.bash_profile
to remove the Minicondadirectory from your PATH environment variable.Remove the following hidden file and folders that may havebeen created in the home directory:
.condarc
