Hello all,

I'm getting the attached errors when I run conda build.

Demo

conda create -n bug_report python=3.8
conda activate bug_report
git clone https://github.com/pybind/python_example.git
cd python_example/conda.recipe
conda build .

  DEPRECATION: A future pip version will change local packages to be built in-place without first copying to a temporary directory. We recommend you use --use-feature=in-tree-build to test your packages with this new behavior before it becomes the default.
   pip 21.3 will remove support for this functionality. You can find discussion regarding this at https://github.com/pypa/pip/issues/7555.
