I've been trying to get Emacs and Clojure to work for the last couple of hours but dammit if it doesn't want to work at all. So, in my blind rage I figured I should delete the .emacs.d/-folder with all the content. And since I'm using OS X I can't see the hidden files and I have no way of restoring them.
I'm also using the newest nightly build from emacsformacosx.com. Specifically the error is about the elpa/package.el-file.
So, ehm, I need help to get Emacs to work again, somehow reset it. And sorry if this question is in the wrong Stackexchange-site, I'm sort of desperate to get this to work. Or just plain mad that it doesn't. Bah.
Check if you have a .emacs file in your home directory. ELPA will stick
(when
(load
(expand-file-name "~/.emacs.d/elpa/package.el"))
(package-initialize))
at the end of this file when it is installed. That's what's probably causing the error.
