问题
I've just installed emacs on my MacBook Pro but when I cast "emacs" on my terminale I receive this type of error :
Emacs-x86_64-10_10[5647:247335] Failed to initialize color list unarchiver: Error Domain=NSCocoaErrorDomain Code=4864 "* -[NSKeyedUnarchiver _initForReadingFromData:error:throwLegacyExceptions:]: non-keyed archive cannot be decoded by NSKeyedUnarchiver" UserInfo={NSDebugDescription=* -[NSKeyedUnarchiver _initForReadingFromData:error:throwLegacyExceptions:]: non-keyed archive cannot be decoded by NSKeyedUnarchiver}
Then emacs opens correctly but I can't compile files because of this error.
回答1:
This is a known error for Emacs on macOS Mojave. Apparently Emacs has been using a deprecated, and now removed, API. You can follow the thread on the "emacs-devel" mailing list.
Edit 25 JUL 2019:
Since people still seem to be getting to this question, patches for this issue were pushed the emacs-26 branch as of Fri, 28 Sep 2018. The latest version of Emacs 26 (or greater) from source or https://emacsformacosx.com/ will work. If you're just now upgrading and you still get the error/crash with the latest Emacs, delete ~/Library/Colors/Emacs.clr and restart your new Emacs. Emacs will recreate a non-corrupted version of that file as documented here.

Apparently the issue, mentioned here, can be fixed just by removing
~/Library/Colors/Emacs.clr
This file will be recreated the next time Emacs is run
EDIT: when you reboot though, it shows up again

Thank you, @Fabrizio-Miano. I lack the reputation to comment on your answer, but it guided me in the right direction. I was able to suppress this error with a simple one-liner added to the end of my init.el. For others who are interested, I just added:
(delete-file "~/Library/Colors/Emacs.clr")
For what it's worth, I placed this in a progn statement so that it occurs after my theme gets loaded. I'm not sure that it makes a difference, but it seemed like a logical thing to do. Perhaps not an ideal solution, but better than waiting for things to get sorted out in the emacs-26 branch.
