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
