如果在 OS X 上安装了 GNU coreutils，又启用了 osx Layer，那么很可能在 dired mode 中使用 SPC f E (sudo edit) 会失败，解决方法：
- 1 代码：
(with-eval-after-load 'tramp-sh
(defun tramp-get-ls-command (vec)
(with-tramp-connection-property vec "ls"
(tramp-message vec 5 "Finding a suitable `ls' command")
(or
(catch 'ls-found
(dolist (cmd '("gnuls" "gls" "ls"))
(let ((dl (tramp-get-remote-path vec))
result)
(while (and dl (setq result (tramp-find-executable vec cmd dl t t)))
;; Check parameters. On busybox, "ls" output coloring is
;; enabled by default sometimes. So we try to disable it
;; when possible. $LS_COLORING is not supported there.
;; Some "ls" versions are sensible wrt the order of
;; arguments, they fail when "-al" is after the
;; "--color=never" argument (for example on FreeBSD).
(when (tramp-send-command-and-check
vec (format "%s -lnd /" result))
(when (tramp-send-command-and-check
vec (format
"%s --color=never -al /dev/null" result))
(setq result (concat result " --color=never")))
(throw 'ls-found result))
(setq dl (cdr dl))))))
(tramp-error vec 'file-error "Couldn't find a proper `ls' command")))))
- 2 删除
~/.emacs.d/.cache/tramp - 3 修改
osx/post-init-exec-path-from-shell@~/.emacs.d/layers/+os/osx/packages.el:
(defun osx/post-init-exec-path-from-shell ()
;; Use GNU ls as `gls' from `coreutils' if available. Add `(setq
;; dired-use-ls-dired nil)' to your config to suppress the Dired warning when
;; not using GNU ls. We must look for `gls' after `exec-path-from-shell' was
;; initialized to make sure that `gls' is in `exec-path'
