Understanding the “Brew Not Found” error

If you're a Mac M1 user, you may have encountered the "Brew not found" error while trying to install a package or software. This error message often arises when you're attempting to use Homebrew, a package manager that enables you to install applications on your Mac.

The "brew not found" error message often indicates that Homebrew is not installed on your system or that it's missing, making it impossible to install or upgrade any packages. The problem typically arises after upgrading your macOS, after installing a new app, or when you try to use an application that requires Homebrew as a dependency.

If you're encountering this error, don't panic! There are multiple ways to fix it, and we've got you covered in our Troubleshooting Guide. Our Guide covers bespoke solutions that are tailored to your exact Mac M1 version and use case scenario.

Common causes of the “Brew Not Found” error

If you're using a Mac M1 and trying to install software packages, you might encounter the "Brew Not Found" error. This error is usually caused by a missing or improperly configured Homebrew package manager. There are several common causes of this error:

  • Missing Homebrew: If you haven't installed Homebrew on your Mac, you won't be able to use it to install software packages. Make sure to install Homebrew using the official installation instructions before proceeding.
  • Incorrect installation path: If you installed Homebrew in a non-standard location, your system may not be able to find it. Verify that Homebrew is installed in the correct location and that your PATH environment variable is properly configured to include it.
  • Outdated Homebrew: If you haven't updated your Homebrew installation in a while, it may be outdated and unable to find the packages you're trying to install. Make sure to update Homebrew using the brew update command before attempting to install any packages.
  • Missing formulae: If you're trying to install a package that isn't available in the default Homebrew formulae, you may get the "Brew Not Found" error. Try searching for the package using brew search or checking the package's documentation for installation instructions that may require a different package manager.
  • Permissions issues: If you don't have the proper permissions to access or modify Homebrew files and directories, your installation may not work correctly. Make sure to run Homebrew commands with the appropriate permissions, such as using sudo when necessary.

    How to troubleshoot the “Brew Not Found” error

To troubleshoot the "Brew Not Found" error on your Mac M1, there are a few steps you can follow that should help you get everything back up and running in no time. Here's a quick rundown of what you should do:

  1. Check your PATH environment variable to see if it includes the directory where Homebrew is installed. This is usually /usr/local/bin. To do this, open a terminal window and run the command echo $PATH. If /usr/local/bin is not listed, you'll need to add it to your PATH. You can do this by opening your shell profile file (usually ~/.bash_profile or ~/.zshrc) and adding the line export PATH="/usr/local/bin:$PATH".

  2. Make sure you have installed Homebrew on your Mac M1 by running the command /bin/bash -c "$(curl -fsSL" in the terminal. If Homebrew is already installed, you may need to update it by running brew update.

  3. If Homebrew is properly installed and you've added its directory to your PATH, but you're still getting the "Brew Not Found" error, try reinstalling Homebrew using the command mentioned above.

  4. If none of these steps work, you may need to check your permissions on your Mac. The error may be related to a permission issue, preventing the terminal from accessing the Homebrew installation directory. You can check and adjust permissions using the command sudo chmod -R 755 /usr/local/bin.

By following these steps, you should be able to troubleshoot the "Brew Not Found" error on your Mac M1 and get everything working as it should. If you're still having trouble, don't hesitate to reach out to the Homebrew community for help. They're a friendly and supportive group and should be happy to assist you with any issues you're experiencing.

Easy code solutions for a quick fix

If you're experiencing the "Brew Not Found" error on your Mac M1, don't panic! There are some easy code solutions you can try to quickly fix the problem.

First, try running the following command in your Terminal:

/bin/bash -c "$(curl -fsSL"

This command will install Homebrew, which is a package manager that allows you to easily install and manage software on your Mac.

If that doesn't work, you can try updating your PATH variable by adding the Homebrew bin directory to it. To do this, run the following command:

echo 'eval "$(/opt/homebrew/bin/brew shellenv)"' >> ~/.zprofile

This command will add the necessary code to your .zprofile file, which is a file that is loaded every time you open a new Terminal window.

Once you've added the code to your .zprofile file, you'll need to restart your Terminal for the changes to take effect. To do this, simply close your Terminal window and open a new one.

Hopefully, one of these code solutions will fix the "Brew Not Found" error on your Mac M1. If you're still having issues, be sure to do some research and check for any compatibility issues with the software you're trying to install. And as always, don't be afraid to experiment and learn through trial and error!


In , encountering the "brew not found" error on your Mac M1 can be frustrating, but there are easy code solutions that can help you quickly resolve the issue. Remember to follow the steps we've outlined and make sure you have the latest version of Homebrew installed. If you're still having trouble, don't hesitate to seek help from online forums or the Homebrew community.
