Could not build wheels for xfoil, which is required to install pyproject.toml-based projects

I'm sorry to hear that you encountered an issue while trying to build wheels for xfoil. This error usually occurs when there are missing dependencies or compatibility issues with the pyproject.toml file.

To resolve this issue, you can try the following steps:

1. Make sure you have all the necessary dependencies installed. Check the documentation or requirements file for xfoil to see if any additional packages are required.

2. Update your pip and setuptools versions to the latest version by running the following commands:

   pip install --upgrade pip
   pip install --upgrade setuptools

3. Try installing xfoil again using the --no-build-isolation flag, which disables the build isolation provided by pyproject.toml. Run the following command:

   pip install --no-build-isolation xfoil

4. If the above steps do not work, you can try installing xfoil using a different method, such as using a pre-compiled binary or building from source. Refer to the xfoil documentation for alternative installation instructions.

If none of these solutions work, please provide more details about the specific error message you encountered, as well as your operating system and Python version. This will help in troubleshooting the issue further.
