BUILD: Unable to compile on Windows 10 with Python 3.10
When downloading the tar ball and executing “py setup.py develop” most of the build succeeds until you ge to the step where it tries to build pandas._libs.indexing, because indexing.c is not in the _libs directory, the build fails with the following error:

Exception: Cython-generated file ‘pandas\_lib/indexing.c’ not found.
    Cython is required to compile pandas from a development branch.
    Please install Cython or download a release package of pandas.

For the record, there is no official release of Pandas for Python 3.10 on Windows or Macintosh, only Linux.

cython is installed:

py -c “import cython; print(cython.__version__)”
0.29.24
