How to Fix the expo cannot be loaded on terminal Error on Windows

If you're working with React Native and Expo, you might encounter an error that prevents you from running the expo start command in your Windows PowerShell. This issue usually arises due to execution policies that restrict script running on your system. Let's dive into the solution step by step so you can get back to building your app as quickly as possible.

Understanding the Problem

The error message you see resembles this:

This indicates that the execution policy on your machine is set to Restricted, preventing any scripts from running, including the one for Expo. This is a security feature in Windows PowerShell, but adjusting this policy will enable you to proceed with your development.

The Solution Step by Step

Here’s how to change your execution policy to allow scripts to run:

Step 1: Open Windows PowerShell as Administrator

Search for PowerShell in the Windows search bar.

Right-click on Windows PowerShell and select Run as administrator.

This step is essential because changing execution policies requires administrative privileges.

Step 2: Check Your Current Execution Policy

Before making any changes, you can check your current execution policy by typing the following command in PowerShell:

You will likely see Restricted as the output. This means that running scripts is currently disabled.

Step 3: Change the Execution Policy to Unrestricted

To enable script execution, you'll need to change the execution policy. Type the following command in PowerShell:

You will receive a prompt asking for confirmation. Press 'Y' and hit Enter to confirm the change. This command changes the policy from Restricted to Unrestricted, allowing the execution of scripts.

Step 4: Verify the Changes

To ensure your new settings are applied correctly, run the following command again:

You should now see Unrestricted as the output. This indicates that you can now run the expo start command without issues.

Always ensure you have proper permissions and be cautious when modifying execution policies, as this could impact your system's security.

If you continue to face issues, don’t hesitate to seek help from the Expo community or check the official documentation for further guidance. Happy coding!
