How can I resolve the issue of getting a “command not found” error for Python in Zsh on macOS Monterey 12.3?

Hey everyone,

I’m currently having a bit of a frustrating issue and could really use your help. I recently switched to Zsh on my Mac running macOS Monterey 12.3, and I’ve been trying to run Python scripts. However, every time I try to execute a python command in the terminal, I get a “command not found” error.

I’ve checked if Python is installed by running `python –version` and `python3 –version`, but it seems like neither of them is recognized. I’ve even tried reinstalling Python using Homebrew, but the problem persists.

I’m wondering if anyone else has run into this issue and knows how to resolve it? Any tips or steps you can suggest would be greatly appreciated! Thanks!

    1. Help with Python on Zsh

      Re: Python Command Not Found in Zsh

      Hi there!

      I totally understand how frustrating this can be, especially when you’re trying to get things up and running. Here are a few steps you can try to resolve the issue:

      1. Check Your PATH: Make sure that the directory where Python is installed is included in your PATH. You can check your PATH by running echo $PATH in the terminal. Usually, Python installed via Homebrew is located in /usr/local/bin.
      2. Install Python with Homebrew: If you haven’t done this yet, you might want to ensure that Homebrew is properly installed and then install Python using the following commands: 
        brew update
brew install python
      3. Check Installed Versions: After installing, check again with python3 --version. If you see it, then you can use python3 instead of python to run your scripts.
      4. Create an Alias: If python3 works but python does not, you can create an alias by adding this line to your ~/.zshrc file: 
        alias python=python3

        After editing, run source ~/.zshrc to apply the changes.

      5. Check Python Installation: If none of the above works, you might want to check where Python is installed: 
        which python
which python3

        This command should show you the path where Python is located. If nothing shows up, Python might not be installed at all.

      Hopefully, one of these steps will help you get Python running in Zsh. Good luck!

      Best,

      Your fellow programmer

      It sounds like you’re encountering a common issue that can occur after switching shells or making changes to your system. First, let’s ensure that Python is properly installed and that your shell is aware of its location. You can check the installation by running the command which python and which python3; this should return the path to the Python executables if they are installed. If you don’t see any output, it indicates that Python might not be in your $PATH. To add the appropriate path, locate where Homebrew installed Python, usually under /usr/local/bin or /opt/homebrew/bin (for Apple Silicon). Once identified, add this path to your .zshrc file by adding the line export PATH="/usr/local/bin:$PATH" (or the corresponding path).

      After updating your .zshrc file, be sure to source it to apply the changes by running source ~/.zshrc. If you’re still facing issues, try reinstalling Python entirely with Homebrew using brew uninstall python followed by brew install python. Additionally, consider checking if Python’s symlink is correctly set up by running brew link --overwrite python. Lastly, verify your installation again by typing python3 --version or python --version. Hopefully, these steps will resolve the issue, and you’ll be back to running your Python scripts smoothly!
