Installing Homebrew and Anaconda on a Mac

Install Homebrew

Run the following command on your terminal to install Homebrew. Homebrew is a package manager for Macs and is used to install useful development tools and software.

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Install Anaconda through Homebrew

1. Run brew install --cask anaconda to install Anaconda
2. Run echo 'export PATH=/usr/local/anaconda3/bin:$PATH' >> ~/.zshrc from your terminal
3. Also run echo 'export PATH=/opt/homebrew/anaconda3/bin:$PATH' >> ~/.zshrc from your terminal
4. Run source ~/.zshrc from your terminal
5. Type conda to ensure that anaconda linked correctly.

If you use bash instead of zsh, replace steps 2 and 3 from above with the following:

• echo 'export PATH=/usr/local/anaconda3/bin:$PATH' >> ~/.bash_profile
• echo 'export PATH=/opt/homebrew/anaconda3/bin:$PATH' >> ~/.bash_profile
• source ~/.bash_profile

If you've already installed anaconda from the installation file from anaconda.org

If you installed Anaconda for only this user, run the following:

• echo 'export PATH=/Users/$USER/anaconda3/bin:$PATH' >> ~/.zshrc
• echo 'export PATH=/opt/homebrew/anaconda3/bin:$PATH' >> ~/.zshrc
• source ~/.zshrc

If you installed Anaconda for all users on your computer, then run the following:

• echo 'export PATH=/opt/anaconda3/bin:$PATH' >> ~/.zshrc
• source ~/.zshrc

If zsh users get "conda not found", then running /opt/homebrew/anaconda3/bin/conda init zsh from the terminal is apparently the way forward w/ zshell since anaconda no longer suggests modifying the path

Thanks! It was helpful.

Dude thank you son much

Thank you! Super helpful!

Thanks dude.

Thank you! Super helpful!

This worked, thank you so much!

If you're using fish shell, run

fish_add_path /opt/homebrew/anaconda3/bin

actually @ryanorsinger & everybody, you should replace steps #2 - #5 with the following very simple
conda init bash
(or check out conda init if you use a different shell.

i found this page because i was struggling after installing brew & conda. the above solved all of my issues.

Thank you !

Agree. This helped me.

conda/conda#13022 (comment)

Thank you for the article!
I would also like to add that if you are using ZSH as your shell or are a Mac user with an M1, M2 chip, etc.
You need to execute the following commands (assuming that Homebrew is pre-installed):

1. brew install --cask anaconda
2. conda init zsh
3. source ~/.zshrc

Then you can execute the command to update conda:

• conda update conda

I don't think conda init zsh will work. It needs to be initialized from the Homebrew location. In the link from @AlifUnseen I found what seems to be the correct instructions:

For people using homebrew to install anaconda (brew install --cask anaconda) instead of manually adding conda to PATH run /(your conda installation path)/bin/conda init zsh which on Apple silicon (M1/M2) is /opt/homebrew/anaconda3/bin/conda init zsh. This adds conda to your PATH in .zshrc and makes sure that you can now use conda and activate conda environments.

Then you can run source ~/zshrc and use conda in your shell.

super helpful, thanks a lot 🙌

super helpful, thanks a lot

While command uname -m returns arm64, brew install --cask anaconda still downloads x84_64 version of Conda instead of arm64 version. Anyone running into this issue?

thanks

thank you!

Great! Thanks :)

thanks! this was exactly what helped me!
