I'm moving to Racket from using Scheme in other environments, and learning
my way around DrRacket via the tried and true method of poking at it to see
what happens. When I do "Show Module Browser" from the View menu, I
get an error. The traceback begins as follows:
Error expanding the program:
expand: namespace mismatch; cannot locate module instance
module: #<module-path-index:"errortrace-key.rkt"
errortrace/errortrace-lib>
use phase: 0
definition phase: 0
for identifier: #<syntax:Applications/Racket
v7.0/share/pkgs/errortrace-lib/errortrace/errortrace-lib.rkt:256:58
errortrace-key>
(binding->module-instance . #f)
(binding-lookup50 . #f)
....
I'm using Racket v7.0. OS is MacOS High Sierra (10.13.6).
The upper definition area of DrRacket contains only the line "#lang racket".
The complete error listing is attached. My question: is this a bug or
does it indicate some failure on my part? Is the Module Browser
trying to reference an uninstalled package/module?
Complete error listing is attached.
Thanks.
