Installation issue with conda on Windows

[mwcraig]

I'm running into an issue trying to create a conda environment on windows. I don't get the error if I create a python-only environment and then pip install sidecar==0.5.1...it only comes up if I conda or mamba install.

The error I get is below -- if the solution is to rebuild the conda package let me know and I can do that.

CondaVerificationError: The package for sidecar located at C:\Users\jv8699qa\Miniconda3\pkgs\sidecar-0.5.1-pyhd8ed1ab_0
appears to be corrupted. The path 'share/jupyter/labextensions/@jupyter-widgets/jupyterlab-sidecar/static/vendors-node_modules_css-loader_dist_runtime_api_js-node_modules_css-loader_dist_runtime_cssW-926fd9.949facbe71846c90da88.js.map'
specified in the package manifest cannot be found.

Looks like .map files are shipped in the package while they should probably not be.
