Conda doesn't find local package to install, although it's present in the environment's conda-bld directory

I have built a conda package from my PyPI package using conda-build.

$ cd
$ conda skeleton pypi climate_indices
$ ll climate_indices/
total 6
-rw-r--r-- 1 DELL 197121  107 Sep 10 10:02 bld.bat
-rw-r--r-- 1 DELL 197121   81 Sep 10 10:02 build1.sh
-rw-r--r-- 1 DELL 197121 1088 Sep  9 15:29 meta.yaml
$ conda-build climate_indices
$ ls -l /c/home/miniconda3/envs/packaging/conda-bld/win-64/
total 73
-rw-r--r-- 1 DELL 197121 58736 Sep 10 13:11 climate_indices-1.0.0-py37h39e3cac_0.tar.bz2
-rw-r--r-- 1 DELL 197121  2091 Sep 10 13:11 index.html
-rw-r--r-- 1 DELL 197121   707 Sep 10 13:11 repodata.json
-rw-r--r-- 1 DELL 197121   417 Sep 10 13:11 repodata.json.bz2
-rw-r--r-- 1 DELL 197121   825 Sep 10 13:11 repodata2.json

I next try to install it into the environment and this step fails:

$ conda install --use-local climate_indices
Solving environment: ...working... failed

To search for alternate channels that may provide the conda package you're
looking for, navigate to

and use the search bar at the top of the page.

It looks to me that it's maybe ignoring the --use-local option. Why is this not working as I expect (i.e. as described here)?
