Hey Alex, I think I mentioned earlier that I can replicate this bug on a fresh install of Guix. Only installing Emacs and emacs-guix to my profile. Can you see if you can replicate it that way?Sent from my Sprint Phone.------ Original message------From: Alex KostDate: Sun, Apr 7, 2019 11:28 AMTo: brettg@posteo.net;Cc: help-guix;Subject:Re: emacs-guix throwing errorsbrettg@posteo.net (2019-04-06 02:59 +0200) wrote:

Sorry, I'm afraid I don't know what causes this error.  I hope I will
face this bug soon, so that I could figure it out.  Maybe it happens
only to people who installed "ghc" package (as the error says about
GHC_PACKAGE_PATH variable), I don't know :-(
