Understanding the Brew Command Not Found on Mac
Mac’s “brew command not found” error occurs when the system cannot locate the brew binary in its path.
Cause of the error
With the brew command acting as a backbone of many functions on your Mac, encountering the “brew command not found” error could leave you scratching your head.
This problem typically crops up due to either an incomplete or incorrect installation of Homebrew or that Brew itself isn’t installed.
Another factor might be that the zsh shell cannot locate the brew binary needed to execute commands.
In essence, it implies that your system is stumbling in its search for this important executable file within its PATH environment variable directory list— a critical repository where Unix systems look for such files.
Impact on system functionality
Mac’s “brew command not found” error can significantly impact your system’s functionality. Without the brew command, you won’t be able to install or manage software packages using Homebrew, which is a popular package manager for macOS.
This means installing and updating various applications and tools that rely on Homebrew might encounter difficulties.
Additionally, if you frequently use a Terminal or a command-line interface, this error can hinder your workflow and productivity.
The inability to access the brew command can prevent you from executing specific commands or scripts that rely on Homebrew’s functionality.
To resolve this issue and restore full system functionality, promptly addressing the “brew command not found” error is crucial by following the suggested solutions and troubleshooting steps outlined below.
Common scenarios where the error occurs
The “brew command not found” error can occur in various scenarios on a Mac system.
Here are some common situations where you might encounter this issue:
- Fresh installation: When Homebrew is not installed on your Mac, attempting to use the brew command will result in the “command not found” error.
- Incorrect installation: If Homebrew was not installed properly or its installation got corrupted, the brew binary may not be located in the expected path, leading to the command not being found.
- Using different shells: The error can also occur when you switch between different shells, such as from Bash to zsh, and the new shell cannot find the brew binary in its designated path.
- System updates or upgrades: Upgrading macOS or updating Xcode can sometimes interfere with the existing Homebrew installation or affect its accessibility, resulting in the “command not found” error.
- M1 Mac architecture: On newer M1 Macs with Apple Silicon, running brew commands directly without proper configuration may trigger the “command not found” error due to compatibility issues with the ARM architecture.
- PATH environment variable issues: If the PATH environment variable is misconfigured or does not include the directory where Homebrew is installed, the system cannot locate and execute brew commands, leading to the error message.

Troubleshooting Steps for the “brew command not found” Error
To troubleshoot the “brew command not found” error, you can follow these steps:
Checking the system path
To troubleshoot the “brew command not found” error on Mac, you can start by checking the system path. The system path is a list of directories where the operating system searches for executable files.
The command will not be found if the brew binary is not in one of these directories.
Here are the steps to check the system path:
- Open a terminal window on your Mac.
- Type the following command and press Enter.
- Look for directories containing the brew binary, such as `/usr/local/bin` or `/opt/homebrew/bin`. Brew is not included in the system path if these directories are missing from the output.
- Verify if Homebrew is installed on your Mac by running this command.
- If Homebrew is installed but not included in the system path, you must add it manually.
- Using a text editor, open your terminal profile file (e.g., `~/.bash_profile`, `~/.zshrc`).
- Add the following line at the end of the file.
- Save and close the file.
Verifying Homebrew installation
To verify the installation of Homebrew on your Mac, follow these steps:
- Open the Terminal application on your Mac.
- Type the command “brew doctor” and press Enter.
- This command will analyze your Homebrew installation and check for any issues or errors.
- If Homebrew is installed correctly, you will see a message stating that your system is ready to brew.
- If there are any problems with the installation, you will receive error messages or warnings indicating what needs to be fixed.
- Pay attention to specific instructions provided in the output to address the issues.
- If you don’t have Homebrew installed, you can install it by typing the command “/bin/bash -c “$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)” && echo ‘eval “$(/opt/homebrew/bin/brew shellenv)”‘ >> /Users/your_username/.zshrc && eval “$(/opt/homebrew/bin/brew shellenv)”‘ >> /Users/your_username/.zshrc” in Terminal and pressing Enter.
- After verifying or reinstalling Homebrew, run “brew doctor” again to ensure everything is set up correctly.
Updating and upgrading Homebrew
To keep your Homebrew installation up to date and ensure you have the latest version of packages, regularly updating and upgrading Homebrew is essential.
Here are the steps to update and upgrade Homebrew on your Mac:
