pip install datadotworld\[pandas\] fails on macOS

[dheerajchand]

Hi,

macOS 10.15.7 , Homebrew Python 3.9

I'm getting a clang and pandas error. clang is installed via Homebrew and is fine. Pandas is fine in the virtualenv, too.

This is the relevant part of the error:

      File "/private/var/folders/2h/qd0400yx26lbw_dr74fyjjv40000gn/T/pip-install-p2t1aktb/pandas/setup.py", line 366, in check_cython_extensions
        raise Exception("""Cython-generated file '{src}' not found.
    Exception: Cython-generated file 'pandas/_libs/algos.c' not found.
                    Cython is required to compile pandas from a development branch.
                    Please install Cython or download a release package of pandas.
