Troubleshooting

Troubleshooting

This section provides solutions to common issues encountered while using PyPositron.

Installation Issues

Problem: PyPositron fails to install

Solution: Ensure you have the latest version of pip installed:

pip install --upgrade pip

If the issue persists, try installing PyPositron in a manual virtual environment:

python -m venv venv
source venv/bin/activate
pip install py-positron

Runtime Errors

Problem: FileNotFoundError for frontend/index.html

Solution: Ensure the frontend/index.html file exists in your project directory. If it is missing, create a new HTML file at that location or copy the default index.html from the PyPositron repository.

Problem: RuntimeError: openUI must be called from the main thread

Solution: Ensure that the openUI function is called from the main thread. Avoid calling it from background threads.

Virtual Environment Issues

Problem: Virtual environment activation fails

Solution: On Linux/macOS, use the following command to activate the virtual environment:

source venv/bin/activate

On Windows, use:

venv\Scripts\activate

If activation still fails, recreate the virtual environment:

python -m venv venv

UI Issues

Problem: UI does not load

Solution: Check the backend/main.py file for errors. Ensure that the openUI function is correctly configured to load the frontend/index.html file.

Problem: JavaScript errors in the browser console

Solution: Debug the JavaScript code in your frontend/index.html file. Use the browser's developer tools to identify and fix errors.
