The bug:
$ echo "conda_build:">>
/.condarc/.condarc$ echo " cache_dir: /opt/conda/conda-bld">>
$ conda config --get conda_build.cache_dir
unknown key conda_build.cache_dir
The diagnosis:
We use nested keys in conda-build, but conda refuses to play ball
because it cares not for our nesting when it looks for the key.
The fix:
Step through the requested, dotted, nested key and rc_config in
lock-step.
The resolution:
$ conda config --get conda_build.cache_dir
--set conda_build.cache_dir /opt/conda/conda-bld
