Troubleshooting

Installation Issues

Multiple Python Versions

If you have several Python installations, Ursina may install to a different one than you’re using in your IDE or script. Ensure you run:

python -m pip install ursina

with the same Python interpreter you launch your code with citeturn0search1turn0search0.

Dependency Conflicts

Pip may struggle choosing compatible Ursina releases when other dependencies conflict. Upgrading pip and installing in a fresh virtual environment often helps:

python -m pip install --upgrade pip
python -m venv venv && venv\Scripts\activate
pip install ursina

Wheel Build Errors

Errors like invalid command 'bdist_wheel' indicate missing build tools. On Windows, install the “Build Tools for Visual Studio.” On Linux/macOS, install python3-dev and build-essential packages.

Import Errors

ModuleNotFoundError: No module named ‘ursina’

Verify Ursina is installed in your current environment. Running your script with python rather than python3 or vice versa can cause this error.

No module named ‘direct’

The direct module is part of Panda3D. Ensure Panda3D is correctly installed alongside Ursina:

pip install panda3d

IDE Configuration

VSCode Not Recognizing Ursina

In VSCode, select the correct Python interpreter in the status bar that matches where Ursina is installed. After that, reload the window

Runtime Warnings

“Error but still running” Message

Some debug prints appear by default but do not affect your game. They originate from Ursina’s internal logging and can be safely ignored.

Platform-Specific Issues

Raspberry Pi Installation Fails

Installing Ursina on Raspberry Pi can fail due to unavailable Panda3D wheels. You may need to compile Panda3D from source or run on a 64-bit OS.
