Hi! It is possible to work around this error <https://debbugs.gnu.org/cgi/bugreport.cgi?bug=45196> by installing emacs as well.
Another workaround is to start guile-studio with EMACSLOADPATH preset to: EMACSLOADPATH=/gnu/store/…-emacs-27.1/share/emacs/27.1/site-lisp guile-studio It seems to me that this /gnu/store/…-emacs-27.1/share/emacs/27.1/site-lisp path is missing in the guile-studio shell script, which only uses tis path from the emacs package: /gnu/store/…-emacs-27.1/share/emacs/site-lisp. Bye Stefan
