When developing applications in Python that utilize libraries like pyproj, you might face unexpected hurdles when converting your code into an executable file for use on another machine. One common issue is the error:
[[See Video to Reveal this Text or Code Snippet]]
This error message typically signifies that the pyproj library's metadata is not being included when creating the EXE, leading to runtime issues. This guide will walk you through the steps to resolve this error effectively, ensuring your application runs smoothly on other computers.
Understanding the Problem
You may encounter this error after you have:
Written your code using the pyproj library.
Converted your Python script to an executable using a tool like PyInstaller.
Despite these steps, if you run the generated EXE file and receive the PackageNotFoundError, it indicates that the necessary metadata for the pyproj package is missing. This issue can prevent your application from functioning as intended, making it crucial to address.
Solution: Including Package Metadata
The good news is that fixing this issue is straightforward! Follow the steps below to include the required metadata when bundling your application.
Step-by-Step Guide
Open Your Command Line Interface: This can be Terminal for macOS or Linux, or Command Prompt/PowerShell for Windows.
Use PyInstaller with the Correct Flags: Instead of the default PyInstaller command you may be using, you need to modify it to ensure package metadata gets included. Here’s the command to run:

--onefile flag: This tells PyInstaller to bundle everything into a single executable file.
--copy-metadata flag: This is essential as it ensures that PyInstaller packs the necessary package metadata along with the executable for all specified libraries, including pyproj.
Rerun the Process: After executing the above command, PyInstaller will create a new executable file. Place that executable on the target machine and try running it again.
Testing the Solution
Once you have created the EXE file using the updated command:
Transfer the new executable to the designated machine.
Double-click to run it and watch for success in executing without errors.
Conclusion
