Hi, I’m trying to install all the Python modules for a Picar X with Rasp Pi4, and I am getting the following error. Any ideas?

ERROR: Failed building wheel for pyaudio DEPRECATION: Building ‘srt’ using the legacy setup.py bdist\_wheel mechanism, which will be removed in a future version. pip 25.3 will enforce this behaviour change. A possible replacement is to use the standardized build interface by setting the `–use-pep517` option, (possibly combined with `–no-build-isolation`), or adding a `pyproject.toml` file to the source tree of ‘srt’.

Meanwhile, we recommend the following steps: Install the latest version of the Raspberry Pi OS. Follow the correct tutorial to install all library codes from this guide: > **[5. Install All the Modules(Important) — SunFounder PiCar-X Kit documentation](https://docs.sunfounder.com/projects/picar-x-v20/en/latest/python/python_start/install_all_modules.html)** If you encounter an error during the first installation of the robot\_hat library, please try running the sudo python3 install.py command again. This often resolves the issue. ---

Okay, I tried running the install command again, and that seemed to work. I will continue with the setup and make sure everything is functional
