I upgraded a few months ago to Emacs 29.1. Everything appeared to work until I tried to open Emacs from a terminal.

Here is the error message

Warning: arch-independent data dir 'c:/Program Files/Emacs/x86_64/share/emacs/27.2/etc/': No such file or directory Warning: Lisp directory 'c:/Program Files/Emacs/x86_64/share/emacs/27.2/lisp': No such file or directory Error: c:/Program Files/Emacs/x86_64/share/emacs/27.2/etc/charsets: No such file or directory Emacs will not function correctly without the character map files. Please check your installation!

It appears that the terminal isn't aware of the upgrade from version 27.2 to 29.1. How do I finish the installation of 29.1?

  • I'm using the Windows terminal app. I tried running emacs --version in the terminal and now find that I've created a new problem. Now the error is "not recognized as a cmdlet..." I had changed the path thinking that was the problem. Same behavior in the emacs shell and the windows shell. Commented Nov 6, 2023 at 18:40

The problem was the path variable. I changed the path to point to the location of emacs.exe C:\Program Files\Eamcs\emacs-29.1\bin.

I can open emacs from a windows terminal now.

Thank you commenters. I couldn't have solved the problem without your comments.

I think the path fixed the problem "by accident". It looks to me you were running a different non-Windows version of Emacs somewhere else on your system because the output above has "/" instead of "\" for filepaths. My guess is you have a mingw system installed that put its Emacs ahead of the Windows Emacs you meant to run (and are now running).
