Part 1: What's Zsh Command Not Found Brew?

Homebrew, also known as brew, is an extremely useful free and open-source package manager for installing software on macOS. It lets you easily download, install, and manage apps, libraries, and other tools from the command line using simple brew commands.

However, you may encounter the error "zsh: command not found: brew" when trying to use brew in your Mac's Terminal app. This means zsh, the default shell in modern versions of macOS, can't find the Homebrew program itself to execute your brew command.

Essentially, your system doesn't know the location to launch Homebrew from. This common "zsh command not found: brew" error generally happens because:

  • Homebrew is not installed or was installed incorrectly
  • The path to the Homebrew executable is not set properly in environment variables
  • The symlinks associating brew with its executable path are broken

Part 3: How to Fix Zsh Command Not Found Brew Error on Mac?

Now let's explore step-by-step solutions to tackle the annoying 'Zsh command not found' error on your Mac. Get ready to make your terminal troubles a thing of the past! Let's get started!

Way 1: Reinstall the Zsh Brew to Fix Zsh Command Not Found Brew

If the basic fixes don’t resolve the “brew command not found” error, taking more drastic steps like a full Homebrew reinstallation often does the trick. Here is a straightforward process to uninstall then re-add Homebrew:

  • In Terminal, run the official uninstall script:

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

    This removes Homebrew while keeping packages.

  • Restart your Mac to fully clear out Homebrew.
  • In Terminal, run the latest install script:

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

    This defaults to the updated Bash platform.

  • Test with “brew —version” to check if the reinstall worked.

Reinstalling can fix path problems and configuration issues with Homebrew installations. While a bit time consuming, it often gets brew running again.

Way 2: Add Brew to the Path Variable

Occasionally the path environment variables get configured incorrectly when first installing Homebrew. You can manually fix this by adding brew back into the shell’s path. Just follow these quick steps:

  • Open Terminal and use this command for Bash:

    $ echo 'export PATH="/usr/local/bin:$PATH"' >> ~/.bash_profile

    Or this for Zsh:

    echo 'export PATH="/usr/local/bin:$PATH"' >> $HOME/.zshrc

  • Replace "/usr/local/bin" with your actual Homebrew install location if different.
  • Source the file to apply the new $PATH:

    $ source ~/.zshrc

  • Check it worked:

    $ brew –version

Adding the brew command location sets the path variable properly. Now zsh knows where to find brew executables when commands run. Quickly update the shell profile and correct the path issue causing "zsh command not found: brew".

add brew to the path variable

Way 3: Correct the Homebrew Installation

In some cases, the path to Homebrew remains misconfigured even after reinstalls. The key is to manually set the correct Homebrew install directory path yourself in the shell profile.

  • In Terminal, set the path for the current session:

    export PATH="/opt/homebrew/bin:$PATH"

  • Make this permanent by appending to the zsh config file:

    echo 'export PATH="/opt/homebrew/bin:$PATH"' >> $HOME/.zshrc

  • Test Homebrew now works:

    brew help

  • If errors persist, uninstall and reinstall Homebrew under /opt/Homebrew using:

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

Be sure to read all output prompts after reinstalling under /opt. Manually fixing the path and reinstallation under an optimal location often resolves the "brew command not found" issue for good.

Way 4: Install Homebrew under /opt/Homebrew

Apple silicon Macs need special treatment when installing Homebrew to handle the differences between M1 and Intel chips. The key is using the optimal location.

  • Run the install script:

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

  • Note the output prompt to add Homebrew to your PATH in .zprofile.
  • Edit .zprofile per the instructions:

    echo 'eval $(/opt/homebrew/bin/brew shellenv)' >> /Users/yourname/.zprofile eval $(/opt/homebrew/bin/brew shellenv)

  • Test with “brew help”.

The /opt location avoids issues between Intel and M1 software. By following the path setup instructions explicitly for M1 during installation, you can correctly configure Homebrew and eliminate the “zsh command not found” error.

Way 5: Install Xcode on Mac to Fix Zsh Command Not Found Brew

Homebrew utilizes some core libraries and command line tools from Xcode under the hood. If Xcode is missing, Homebrew itself may fail.

install xcode

  • Check if Xcode is installed:

    /usr/bin/xcodebuild -version

    Look for output showing the Xcode version.

  • If installed, open Xcode and enable Command Line Tools in Preferences.
  • If Xcode isn't installed, get it from the App Store or Apple Developer site.
  • Once Xcode is set up, run:

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

This reinstalls Homebrew using the Xcode command line tools.

Many Brew issues arise from lacking dependencies. Confirm Xcode's presence and integration to enable command line functionality Homebrew requires. An Xcode install or reinstallation of Homebrew after verifying Xcode tools often resolves the root cause.

Part 4: Frequently Asked Questions

Q1: Why is brew command not found on Mac?

Ans: The "brew command not found" error appears because your Mac can't find the Homebrew install location. This happens if Homebrew is not properly installed or its executable path isn't set correctly.

Q2: How do I fix command not found on Mac?

Ans: To fix a command not found error, ensure the command exists on your system and add its install directory path to your shell profile PATH environment variable so the shell can locate executables.

Q3: Can I use zsh with Homebrew?

Ans: Yes, zsh is the default shell on modern MacOS versions and fully supports Homebrew. Fixes involve reinstalling Homebrew properly for zsh or correcting the zsh path variable.

Q: How to install brew on Mac command?

Ans: Follow these steps to install:

  • Install Command Line Tools by running xcode-select --install
  • Install Homebrew with:

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

Then follow the script prompts to configure PATH so zsh can locate brew. The xcode-select command handles dependencies, while the Homebrew script downloads brew, adds it to PATH, and sets up zsh integration.
