How to Fix the APP_PORT Issue in Laravel Sail on Windows 10

Laravel Sail offers a fantastic development experience for PHP developers. However, you might hit a snag when trying to set environment variables, especially under Windows 10. If you’ve encountered the following error while setting the APP_PORT in your .env file:

Don’t worry! In this guide, we’ll explore the solution in detail, making it clear and easy for you to follow along. Let's dive in!

Understanding the Problem

When you define the APP_PORT variable in your .env file for a Laravel project using Sail, you expect it to configure your application without any issues. Here's a sample of how your .env file might look:

Upon running the command sail up, you might encounter an error related to the docker-compose.yml file, which expects the ports to be defined correctly. The root cause of this error can be traced back to how line endings are handled in files on different operating systems.

Why This Happens on Windows

The main issue lies in how Windows handles line endings (CRLF) compared to Unix-based systems like Ubuntu (LF). Since the Laravel Sail environment relies on Unix-style line endings to interpret the environment variables correctly, Windows users may face difficulties, leading to the errors mentioned above.

Additional Information

You might see messages similar to the following, indicating a problem with the .env file or other scripts:

Solution: Changing End-of-Line (EOL) Format

To solve this issue, you need to change the EOL format of your .env file from CRLF to LF. Here's how to do that:

Step-by-Step Guide

Open the .env File:

Use a code editor that allows you to set the EOL format, such as VSCode or Notepad+ + .

Change the EOL Format:

In VSCode: Open the Command Palette (Ctrl + Shift + P), and type "Change End of Line Sequence". Select "LF".

In Notepad+ + : Go to Edit EOL Conversion and select Unix (LF).

Apply Changes to Other Files:

You may also need to change the EOL format in the following files:

Ensure they are all converted to LF as well.

Run Sail Again:

After making these changes, try running the command sail up again.

Conclusion

By following these steps to change the EOL format in your environment files, you should no longer face issues with setting the APP_PORT variable on Windows. This solution highlights an important aspect of cross-platform development and reminds us of the differences between Windows and Unix systems.
