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

As an AI language model, I do not have access to your local machine and the necessary environment to provide a specific solution. However, here are some general troubleshooting steps that you can follow:

1. Ensure that you have all the necessary dependencies installed on your system, including proj, geos, and gdal.

2. Make sure that you have the latest version of pip and setuptools installed.

3. Try installing cartopy using a different installation method, such as conda or from the source.

4. If the issue persists, try upgrading your Python version or creating a new virtual environment.

5. If none of the above solutions work, try reaching out to the cartopy community or creating a GitHub issue for further assistance.
