How to Create an exe File from a Django Project Using PyInstaller

Creating an executable (.exe) file from a Django project can be a challenge, especially when dealing with server applications. If you’ve run into errors while trying to bundle your Django application with PyInstaller, you are not alone. One common issue is running the Django development server properly within the executable. In this post, we’ll explore how to tackle this problem step-by-step.

The Problem

Your goal is to generate an .exe file that starts the Django development server and automatically opens the browser to your project's homepage. You created a start.py script for this purpose, but upon creating the executable with PyInstaller, you encountered an IndexError related to the runserver command.

Here’s a brief look at the code you originally wrote:

When you ran the generated executable, you got an error like this:

Understanding the Solution

The issue arises due to the use of the reloader feature of Django's development server. When creating an executable, it appears that the reloader is incompatible with how executable files handle changes.

The Fix

To resolve this problem, you need to modify your run_server function to include the --noreload parameter. Here’s how you can adjust your code:

Why the Change?

The --noreload option tells Django:

Don’t restart if I change the Python code. This is critical when running inside an executable, as the executable doesn’t handle the same way as a script run directly in a terminal. This option helps avoid complications arising from the reloader's child processes and execution issues.

Steps to Create Your Executable

Modify your start.py file with the --noreload argument as shown above.

Run PyInstaller to create the executable:

Run the generated .exe file that can be found in the dist directory, e.g., ./dist/start.

Conclusion

Creating an .exe file from a Django project can seem daunting, but with a few tweaks to how Django's runserver command is executed, you can avoid common pitfalls. By using the --noreload option when running your server, you can effortlessly bundle your Django application into a standalone executable.
