Mac Command Not Found

Are you getting frustrated by the command not found error message on your Mac? It can certainly become a pest when your laptop is slow while you use your Mac for business or leisurely browse the internet. Nobody likes interruptions as well as the risk of data being unsaved, right?

 

But don't worry, we understand your struggle. Which is why, in this article, we’ll address how to troubleshoot the Mac command not found message in detail.

 

Let's begin by identifying the possible reasons for the command not found error message to show on a Mac.

  • Incorrect path settings: The command might not be accessible due to an incorrect configuration in the system's PATH variable
  • Missing or corrupted binaries: If the command's executable file is missing or corrupted, the system cannot locate it
  • Typo errors: A simple typo in the command syntax can trigger the command not found error
  • Package or software not installed: Certain commands rely on specific packages or software that might not be installed on your Mac.

Before we start:

 

Consider the possibility that a specific app might be malfunctioning, and thus, causing the command not found error message. To ensure all apps are running smoothly and to help prevent future errors, we recommend using MacKeeper's Update Tracker. This will keep your apps up-to-date and fix any app-related issues, and in turn, will ensure a stress-free Mac experience.

 

Here are the instructions to use MacKeeper's Update Tracker:

  1. Download and open the MacKeeper app on your Mac
  2. Find and click on the Update Tracker option from the MacKeeper's main menu
  3. Click on the Scan for Updates button to allow MacKeeper to quickly scan and detect any outdated apps. Once the scan is complete, MacKeeper will present a list of apps that require updates
  4. To update all the apps at once, simply click on the Update All button. Alternatively, you can choose to update specific apps by ticking the box next to the particular app you want to update and then click Update.

  1. Verify command syntax for any typos or errors
  2. Ensure the necessary packages are installed on your Mac

Check spelling

One of the most common reasons for the command not found error is incorrect syntax. Even a small typo can cause this frustrating issue. To fix it, carefully check and review the command you entered, looking for any spelling errors or mistakes in the syntax.

 

To avoid the command not found error, follow these recommendations:

  • Verify the correct spelling of the command
  • Check for proper spacing and punctuation
  • Make sure the correct spellings, spacing and punctuation are consistent
  • Look for missing characters or extra symbols
  • Refer to the official documentation for the correct command syntax.

Have you verified that all your spelling is correct? Then move to the next section about the package installation.

Make sure the package is installed

If the command not found error message persists, it could be due to the necessary package not being installed on your Mac. Certain commands require specific packages to function correctly.

 

Here's how to check if the required package is installed:

  1. Open the Terminal app on your Mac
  2. Enter the command associated with the package you suspect is missing. Normally, it’s $PATH. Then press Enter
  3. If the package is not installed, you'll see an error message indicating the package is missing.
To locate and launch the Terminal application on a Macbook device, use the Launchpad and search function.
Step 1. Find and open Terminal
Enter the $PATH command in Terminal on a Macbook device to be able to configure environment variables for system paths.
Step 2. Enter the $PATH command
To finalize the modification of the $PATH environment on a Macbook device using Terminal, press down on the Enter key.
Step 3. Press Enter to finalize

If you do encounter a missing package error, follow these steps to install it to the appropriate folder:

  1. Identify the name of the missing package from the error message
  2. Use the package manager appropriate for your macOS version
  3. Install the package by entering the command specific to the package manager.

Make sure to regularly update your package manager to keep all packages up-to-date.

Set $PATH environment

Despite most packages setting up the path automatically, occasionally users might encounter the command not found error message due to path-related issues. In such cases, manual configuration of the path environment becomes a necessity.  

 

Here's a step-by-step guide on how to do it:

  1. Access the Terminal application on your Mac by clicking the Launchpad icon in your Dock, type Terminal in the search field, and then select Terminal from the search results
  2. After launching Terminal, open the Preferences from the Terminal menu
  3. In the Preferences window, find and select the Shell Profiles or Profiles tab
  4. Depending on your macOS version and the shell you're using (bash or zsh), locate and edit the respective profile file: bash_profile or zshrc
  5. Within the selected profile file, add the correct PATH configuration. Follow the proper syntax while adding the PATH
  6. Save the changes to the profile file and close the Terminal. Reopen it to apply the updated PATH configuration.

By following these steps, you can configure the $PATH environment correctly, and the command not found mac error should be resolved.

To set $PATH environment, you need first to launch the Terminal application on your Macbook using Mac's Launchpad and search feature
Step 1: Find and Launch Terminal
Access the Terminal Preferences menu on your Macbook for advanced configuration, as your second step
Step 2: Open Preferences in the Terminal Menu
Navigate to Shell Profiles or Profiles tab in Terminal Preferences on your Macbook to proceed with further setting up
Step 3: Find and select Shell Profiles or Profiles tab
Locate and edit the relevant shell tab after clicking on The Run Command box to be able to modify path configuration
Step 4: Tick the Run command box
Edit profile file to insert the accurate PATH configuration on your Macbook using Terminal. In our case, zsh was replaced with zshrc
Step 5: Type the correct PATH configuration

Now, let's move on to checking if any missing libraries are the reason for your command not found on Mac.

Check if any libraries are missing

Some commands may require specific additional libraries to function correctly. If the required libraries are missing, it can be the reason for the persistent command not found message.

 

Here's how you can check whether the necessary libraries are installed:

  1. Launch the Terminal application on your Mac
  2. Once the Terminal is open, type in the command that you think might be causing the command not found error. For example, you could try entering git or python. The Terminal will then attempt to execute the command
  3. If the error message indicates that a particular library is missing, you’ll need to install it.

If you’re missing libraries, here’s how to re-install them:

  1. Note down the name of the library mentioned in the error message
  2. Utilize the appropriate package manager for your macOS version. For instance, let’s take Homebrew as example. Enter the following command in Terminal: /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
  3. Enter your password
  4. Presss Enter to install the missing library
  5. After installation, re-run the initial command to check if the error persists.
Launch Terminal on Mac in order to find the missing libraries. Find the Terminal app in the Utilities folder or use the search function in your Launchpad
Step 1. Find and open Terminal
Execute the Homebrew Command and Enter your password in order to Verify the Presence of the Required Library that may need to be reinstalled.
Step 2. Enter the Homebrew command typed above
To confirm the action, when checking if any Libraries are missing and require reinstallation, press the Enter key to continue.
Step 3. Press Enter to continue

Note from our team: 

 

This command spelling is suitable for MacOS Ventura and MacOS Monterey. To install the Homebrew library on the other macOS version, you need to enter the other command details:

  • For macOS Catalina / Mojave / Big Sur:

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

  • For macOS High Sierra / Sierra / El Capitan:

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

 

Now, we've covered the steps to check for and install any missing libraries, let's move on to the very last resort solution to fix an error message — reinstalling masOS.
