无法安装已安装撤消树的新框架

我使用undo-tree 0.6.5(来自Elpa),并且在大多数情况下效果很好。但是,如果尚未在缓冲区上调用C-x-u,则从该缓冲区我无法打开新框架。如果我做C-x-5-2,Emacs会打开` Backtrace 缓冲区:

Debugger entered--Lisp error: (wrong-type-argument undo-tree nil)
  signal(wrong-type-argument (undo-tree nil))
  undo-tree-current(nil)
  (undo-tree-node-previous (undo-tree-current buffer-undo-tree))
  (and undo-tree-mode (not buffer-read-only) (not (eq t buffer-undo-list)) (undo-tree-node-previous (undo-tree-current buffer-undo-tree)))
  x-create-frame(((visibility) (vertical-scroll-bars . left) (reverse . t)))
  x-create-frame-with-faces(((vertical-scroll-bars . left) (reverse . t)))
  #f(compiled-function (params) #<bytecode 0x1fdd4b1bc7bf>)(((vertical-scroll-bars . left) (reverse . t)))
  apply(#f(compiled-function (params) #<bytecode 0x1fdd4b1bc7bf>) ((vertical-scroll-bars . left) (reverse . t)))
  frame-creation-function(((vertical-scroll-bars . left) (reverse . t)))
  make-frame()
  make-frame-command()
  funcall-interactively(make-frame-command)
  call-interactively(make-frame-command nil nil)
  command-execute(make-frame-command)

然后,我执行C-x-u,因此创建了与该缓冲区相关的undo-tree缓冲区,然后可以创建其他帧。

是否有解决方法?

编辑:它还禁止使用菜单。当我尝试单击任何菜单项时,都会显示相同的消息。

好的,所以我知道了。我使用的undo-tree的ELPA版本为0.6.5。因此,几天前,我注意到开发人员在其git存储库中有了一个新版本0.6.6。我在本地安装它,问题就消失了!

首先,获取git存储库的副本:

$ cd ~/.emacs.d
$ git clone http://www.dr-qubit.org/git/undo-tree.git

然后将其添加到您的Emacs配置中:

(load "~/.emacs.d/undo-tree/undo-tree.el")
(require 'undo-tree)
(global-undo-tree-mode)
