Run Python scripts on macOS, they said—it’ll be easy. But after the tenth “file not found” error, I was ready to toss my laptop. Sound familiar?

I still remember the moment—trying to demo a quick Python script during a call, only to be met with that dreaded "python: can't open file" error. I knew the script worked. I just didn’t know the path to it by heart. So there I was, scrambling to cd into the right folder like it was 2005, while the moment slipped away.

If you’ve ever had to dig through layers of directories just to run a simple Python file, you know how annoying—and oddly disempowering—it feels. Especially on macOS, where Terminal is supposed to be your friend.

I finally got tired of the mess and set up a clean, one-time solution that lets me run Python scripts from anywhere in the Terminal—globally, instantly, and without touching aliases or bloated PATH hacks.

Want to clean up your workflow and never see that “file not found” error again?

Keep reading—this fix takes 5 minutes and saves hours.

Why Python Scripts Fail to Run Globally

When you try to run a Python script in the Terminal, macOS needs to know where to find it. By default, Terminal only looks in certain directories—meaning if your script isn’t in one of them, you get an error. This is because the system doesn’t automatically recognize your custom script locations. It’s a common issue that slows down development and testing.

Why Running Python Scripts from the Terminal Matters

1. Efficiency in Workflow:
   Jumping between directories to find a script can become tedious, especially if your project has multiple subfolders. Being able to run a Python script from any directory minimizes these interruptions, allowing you to focus on coding.
2. Enhanced Automation and Scripting:
   Automating tasks with Python is a common practice, whether for data scraping, system management, or CI/CD workflows. Running these scripts seamlessly from the terminal makes it easier to integrate them into cron jobs or scheduled tasks without worrying about relative paths.
3. Consistent Development Environment:
   Many developers use virtual environments to isolate dependencies for different projects. Learning how to run scripts correctly ensures your Python executables and libraries are accessed reliably, even if you switch directories mid-session.
4. Remote Access and Deployment:
   Running scripts efficiently via the terminal becomes critical when managing remote servers. Knowing how to invoke your Python code from anywhere allows you to deploy updates or run maintenance scripts remotely with ease.
5. Improved Collaboration and Version Control:
   Working in teams often means navigating between multiple repositories and directories. If your scripts can be executed from anywhere, onboarding team members and running tests locally becomes a smoother process.

How to Run Python Scripts Anywhere on Mac Terminal

The simple solution? Add your script directory to your system’s PATH. This tells your Mac to look in your custom folders whenever you try to run a script, eliminating those pesky “file not found” errors.

Step 1: Create a Directory for Your Scripts

Start by creating a directory where you will store your Python scripts. You can place this directory anywhere you prefer.

#!/usr/bin/env python3
import os
import sys

Make sure you have the shebang on top. This preloads the python3 interpreter and all other libraries declared. If you don’t do this, you will get a lot of errors believe me.

This is the shebang: !/usr/bin/env python3

Step 2: Add the Directory to Your PATH

• Edit your shell profile file (e.g., ~/.bash_profile for Bash or ~/.zshrc for Zsh) using a text editor like nano or vim.
• Add the following line to your profile file, replacing /path/to/your/scripts with the actual path to your script directory:

nano ~/.bash_profile  # For Bash

Save the file and exit the text editor.

Step 3: Source Your Profile

To apply the changes immediately, source your profile file:

export PATH="/path/to/your/scripts:$PATH"

source ~/.bash_profile  # For Bash

Step 4: Make Your Scripts Executable

Ensure that your Python scripts have executable permissions. Use the chmod command:

chmod +x /path/to/your/scripts/your_script.py

Replace your_script.py with the name of your Python script.

Step 5: Test Your Scripts

You should now be able to run your Python scripts from any directory without specifying the full path:

your_script.py

Step 6: Persistence After Reboot

The changes to your PATH environment variable should persist across reboots. Be cautious not to accidentally remove or modify the lines you added to your profile file.

By following these steps, your Python scripts will be universally accessible from any directory on your Mac, even after a reboot.

Step 7: Testing Your Setup

To make sure everything is working, create a simple Python script. For example, create a test.py file in your scripts directory with this content:

print("Python script running from anywhere!")

Then, try running it from any folder in Terminal by simply typing:

python test.py

If you see the message “Python script running from anywhere!” in the Terminal, congratulations! Your setup is complete, and you can now run Python scripts globally.
