如何使emacs加载ess

Question

I installed emacs 26 via flatpak and ess using sudo apt-get.

Currently my ess exists at /usr/share/emacs/site-lisp/elpa-src/ess-17.11 and I put in my .emacs file (load "/usr/share/emacs/site-lisp/elpa-src/ess-17.11/") . When I run emacs, I get the following warning:

Warning (initialization): An error occurred while loading ‘/home/yannik/.emacs’:

File is missing: Cannot open load file, No such file or directory, /usr/share/emacs/site-lisp/elpa-src/ess-17.11/

However, this directory clearly exists. How do I get emacs to detect ess? I've tried everything, '(require ess-site) didn't work either.

Answer 1

The function load loads a single Emacs Lisp file. What you want to do here is make an entire directory accessible, which you'd do by adding it to the load path:

(add-to-list 'load-path "/usr/share/emacs/site-lisp/elpa-src/ess-17.11/")

After that, you should find that (require 'ess-site) works - it will find the ess-site module in that directory.

That said, you might find it easier to install ESS using Emacs' package manager. Follow the instructions for activating the MELPA package archive , and then type Mx list-packages and install ess from the list. Emacs will download the package, copy it to ~/.emacs.d/elpa , and arrange to load it.
