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

This error message usually occurs when there is an issue with building the `pycurl` package during installation.

Here are a few things you can try to resolve this issue:

1. Make sure that all the required dependencies for building `pycurl` are installed on your system. You can check the list of dependencies on the official `pycurl` website.

2. Ensure that you have the latest version of `pip` installed on your system. You can upgrade `pip` by running the command `pip install --upgrade pip`.

3. Try installing `pycurl` using the wheel package instead of building from source. You can download the appropriate wheel file from the `pycurl` website and install it using the command `pip install /path/to/wheel/file`.

4. If none of the above solutions work, you can try installing `pycurl` using a package manager like `apt-get` or `brew` depending on your system.

I hope one of these solutions helps you resolve the issue and successfully install the required package.
