Did anyone use undo tree in spacemacs? I configured it in spacemacs

 (global-undo-tree-mode 1)

but it doens't work. how to let it work?

It shows the error message of "unrecognized entry in undo list undo-tree-canary"

  • This GitHub issue thread suggests that this was a known issue for a while, but the bug was fixed. Can you pull the latest version of undo-tree.el from MELPA, or failing that, straight from GH, and see if it goes away? Commented Jul 6, 2015 at 7:06
  • I am using the latest spacemac 0.103, but still have such issue

This works on the latest develop, (fresh installation). open undo-tree-visualise with SPC a u. be sure that you have the minimum emacs version:

(defconst spacemacs-emacs-min-version   "24.3" "Minimal version of Emacs.")
