so I ran:
rez pkg-cache
and got:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
usage: rez pkg-cache [-h] [-a URI [URI ...] | --logs | -r URI [URI ...] |
--clean]
[-c {status,package,variant_uri,orig_path,cache_path} [{status,package,variant_uri,orig_path,cache_path} ...]]
[-f] [-v]
[DIR]
rez pkg-cache: error: DIR must be specified, as there is no configured 'cache_packages_path'
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
So it seems that the setting I have in my REZ_CONFIG_FILE is not being read.
I think this may be a bug? I have checked that the other values in the file are being read, and they are.
