Commonly Asked Questions (FAQs) About zsh: command not found: brew
Q1: Why does the ‘command not found’ error pops up on my Mac’s terminal?
This error often arises when the system can’t locate the command you’re trying to run in its set PATH. This could be because the command doesn’t exist or it’s not installed where the system expects it to be.
Q2: How can I add a directory to my PATH?
You can add a directory to your PATH by modifying the .zshrc or .bashrc file in your home directory. Add a line that exports the new PATH, including the directory you want to add.
Q3: How do I reinstall Homebrew?

Q4: Why is my macOS terminal returning ‘zsh: command not found: brew’?
This error indicates that your shell (zsh) doesn’t know the brew command because it’s not in your PATH, or Homebrew isn’t installed on your Mac.
Q5: What should I do if my shell doesn’t recognize the brew command after Homebrew installation?
Ensure that Homebrew is correctly installed and that the Homebrew directory is in your PATH. If you installed Homebrew but haven’t closed and reopened your terminal, try that. The new PATH
information will be available in a new terminal session.
Q6: Why am I seeing the ‘zsh: command not found: brew’ error?
This error typically occurs when the shell cannot locate the brew command. This can be due to Homebrew not being installed or the body not knowing where to find it.
Q7: What’s the difference between .bashrc and .zshrc?
.bashrc and .zshrc are configuration files for Bash and Zsh shells, respectively. These files are executed when a new shell session is started, and they set up your shell environment (like defining shell variables, defining the shell prompt, etc.).
Q8: How can I switch back to Bash from Zsh?
You can switch back to Bash by typing
chsh -s /bin/bash in the terminal. You’ll need to enter your password to confirm the change.
Q9: How can I ensure I have the latest version of Homebrew installed?
You can update Homebrew by typing
brew update in the terminal. This will fetch the newest version from the Homebrew GitHub repository.
Q10: Is there a difference between installing Homebrew on an Intel Mac versus a Mac with an M1 chip?
Due to the architectural differences, Homebrew is installed in a different directory on Macs with an M1 chip (/opt/homebrew) compared to Intel Macs (/usr/local). This can cause the zsh: command not found: brew error on M1 Macs if the shell doesn’t know where to find the brew command.
