Looks like this can be solved if you use the Anaconda build: conda install -c conda-forge python-flint.

[oscarbenjamin]

For now pip install python-flint is unlikely to work. It will work if:

1. You have flint and all the other associated C libraries installed and configured with the appropriate paths.
2. You have a supported C compiler installed.
3. You have Python plus the dev headers installed.

Unless you go out of your way to set all of that up then pip install will fail. There has been some progress towards making wheels for Linux and OSX but not Windows.

In the meantime it is best to use conda unless you want to build this yourself (which is not actually that difficult on Ubuntu).

I'm going to close this as a duplicate of #1.

    `numpy.distutils` is deprecated since NumPy 1.23.0, as a result
    of the deprecation of `distutils` itself. It will be removed for
    Python >= 3.12. For older Python versions it will remain present.
    It is recommended to use `setuptools < 60.0` for those Python versions.
