问个elpy安装后的warning问题

Emacs-general
1

用的Emacs版本是28.0.50，系统是Ubuntu18.04.2。现在已经安装了elpy，自动补全似乎已经可以了，但是在操作过程冲minibuffer里经常会出现一个warning：

error in process filter: Symbol’s function definition is void: eldoc-docstring-format-sym-doc

这造成了操作过程中会有卡顿的现象。请问有没有高手遇到过这个情况？非常感谢！

下图是我elpy-config内容

饿，刚才去查了一下，安装了一个eldoc-eval的插件。只是抱着试一试的态度，但是还是没有解决，哪位大神能帮一下忙？

这个和 elpy 没关系，是 emacs 28 里的 eldoc.el 的问题

(defun eldoc-docstring-format-sym-doc (prefix doc &optional face)
  "Combine PREFIX and DOC, and shorten the result to fit in the echo area.

When PREFIX is a symbol, propertize its symbol name with FACE
before combining it with DOC.  If FACE is not provided, just
apply the nil face.

  (when (symbolp prefix)
    (setq prefix (concat (propertize (symbol-name prefix) 'face face) ": ")))
  (let* ((ea-multi eldoc-echo-area-use-multiline-p)
         ;; Subtract 1 from window width since emacs will not write
         ;; any chars to the last column, or in later versions, will
         ;; cause a wraparound and resize of the echo area.
         (ea-width (1- (window-width (minibuffer-window))))
         (strip (- (+ (length prefix) (length doc)) ea-width)))
    (cond ((or (<= strip 0)
               (eq ea-multi t)
               (and ea-multi (> (length doc) ea-width)))
           (concat prefix doc))
          ((> (length doc) ea-width)
           (substring (format "%s" doc) 0 ea-width))
          ((>= strip (string-match-p ":? *\\'" prefix))
           doc)
          (t
           ;; Show the end of the partial symbol name, rather
           ;; than the beginning, since the former is more likely
           ;; to be unique given package namespace conventions.
           (concat (substring prefix strip) doc)))))

加到配置里试试

多谢大神！！！！把配置粘贴进去好，似乎没有问题了！！我试一段时间后再看看。非常非常感谢！！！

请问这个具体是什么问题？
