Failed to install numcodecs with pip on Py39 and Windows 10

Version and installation information

Please provide the following:

• Value of numcodecs.__version__
• Version of Python interpreter: Python 3.9
• Operating system (Linux/Windows/Mac): Windows
• How NumCodecs was installed (e.g., "using pip into virtual environment", or "using conda") pip in a conda environment

Also, if you think it might be relevant, please provide the output from pip list or
conda list depending on which was used to install NumCodecs.

You should be able to see which version of numcodecs was attempting to be installed in the pip install log. That would be very helpful.

[eigenP]

The version was numcodecs-0.9.1

I think this is now resolved -- waiting on confirmation it was an env / pip caching issue.
