I am not sure to understand your question. I am guessing… :-)
Once you are in:
guix package -p $GUIX_ENVIRONMENT -I
but this is no robust and for example it does not when the environment
is created with --container or --pure; because ’guix’ does not exist by
default.
Otherwise, give a look at the optioj --root.
All the best,
